feat: user-crafted scheduled announcements (custom_announcements)

Browse source 
Free-text broadcasts the owner types straight into the GUI on a clock-slot
schedule (daily / interval_days / weekly / monthly) -- no placeholders, no
data sources, no templating, no SQL from the user.

- v30 migration: custom_announcements table (own explicit channel list per
  row, new rows start disabled).
- CustomAnnouncementScheduler (notifications/scheduled/custom_announcements.py):
  60s tick modelled on ReminderScheduler; monthly day-of-month clamped via
  calendar.monthrange; restart-safe dedup keyed on the local calendar date
  of last_sent_at; spacing_seconds roll-call pacing between announcements
  firing in the same tick.
- Dispatcher.dispatch_scheduled_custom_broadcast(): delivers to the
  announcement's own channel list (no toggle/region_routes matrix), one
  mesh_broadcasts_out audit row per target, cold-start grace.
- New announcement_routes.py router: GET/POST/PUT/DELETE /api/announcements
  + POST .../preview (wire text + char/byte count, never sends). No
  send-now endpoint anywhere.
- Wired into notifications/pipeline/__init__.py (alongside ReminderScheduler)
  and dashboard/server.py; single_packet_max_chars runtime override added
  in main.py's budget list.

57 new tests (recurrence kinds, Feb-29/28 clamp, restart-safe dedup, pacing,
budget truncation, full input validation, multi-target audit rows, no
send-anywhere guarantee). Full suite: 2090 passed, 0 failed (up from 2033
baseline), 9 pre-existing warnings.

"""Custom scheduled-announcement REST API (v30 custom_announcements table).
New resource type (owner-authored free-text broadcasts on a clock-slot
schedule -- see notifications/scheduled/custom_announcements.py), so this is
a NEW router file rather than an extension of notification_routes.py:
notification_routes.py's CRUD-shaped endpoints (region-routing, rules) are
all config-file-backed (save_section/load_config over YAML), while
announcements are individual SQLite rows with their own id, closer in shape
to adapter_config_routes.py's raw get_db()/HTTPException style -- which this
file follows (grouped list, per-row GET/PUT/DELETE, explicit 400s with a
clear message per bad field, no ORM).
Endpoints:
GET /api/announcements -- list all, newest first
POST /api/announcements -- create (ALWAYS starts disabled)
PUT /api/announcements/{id} -- partial update (validated as a whole)
DELETE /api/announcements/{id} -- delete
POST /api/announcements/{id}/preview -- exact wire text + char/byte
count against budget.
NEVER sends.
There is deliberately NO "send now" / test-send route anywhere in this file.

Unlike dispatch_scheduled_fire_broadcast / dispatch_scheduled_roads_
broadcast (which resolve channels via a toggle + region_routes
matrix), a custom announcement carries its OWN explicit destination
list -- set by the owner in the GUI, never derived from a toggle or
a region. Every entry in `channels` is delivered independently and
gets its OWN mesh_broadcasts_out audit row: an announcement with N
mixed Meshtastic/MeshCore targets produces N delivery attempts and N
audit rows. There is no cap on N and no "primary channel" concept.
channels: list of {"transport": "meshtastic"|"meshcore",
"channel": <int index>|<str name>,
"name": <optional display name, ignored here>}.
A target with an unrecognised transport is logged and skipped. A
target whose channel is valid in SHAPE but no longer configured on
the live radio is NOT a hard failure -- create_channel()/deliver()
already logs a warning and returns False for that case (missing
connector, unset meshcore_channel, no meshcore transport, etc.); this
method adds its own warning on top and moves on to the next target,
so one stale MeshCore channel never aborts the rest of the
announcement.
Fan-out pacing: sends are issued one target at a time, same as
dispatch_scheduled_fire_broadcast's `plan` loop. Each send goes
through create_channel() -> connector.send_message_async() ->
RadioSendQueue, which already applies that transport's inter-packet
jitter -- so multi-target announcements are naturally paced without
a second spacing mechanism here.
source_event_table is always "custom_announcements";
source_event_pk is f"{announcement_id}:{slot_key}" so the audit
trail carries a key unique per (announcement, fired slot) rather
than colliding across sends of the same announcement on different

Modelled on ReminderScheduler's clock-slot tick loop

daily -- fires every day at time_of_day.
interval_days -- fires every N days, counted from the LOCAL CALENDAR
DATE (in the announcement's own timezone) of
created_at. created_at's date is day 0; day N, 2N, 3N...
are eligible. Documented anchor choice: created_at
rather than "now" so the cadence is stable and doesn't
drift if the scheduler is down for a while -- an
announcement created on day 0 with interval_days=2
always lands on days 0, 2, 4, ... relative to its own
creation date, never renumbered by a restart.
weekly -- fires on days where dow_mask[local_weekday] is True.
dow_mask is Mon-first (index 0 = Monday .. 6 = Sunday),
matching Python's datetime.weekday().
monthly -- fires on day_of_month, CLAMPED to the last day of the
local month (calendar.monthrange) so day_of_month=31
fires on Feb 28 (or 29 in a leap year), Apr 30, etc.
Dedup (restart-safe, no double-send on a slot)
-----------------------------------------------
Every schedule_kind fires AT MOST ONCE per local calendar day (the
recurrence math above decides WHICH days are eligible; time_of_day is the
only slot on an eligible day). That makes "the concrete local datetime of
the slot" reducible to just the local CALENDAR DATE in the announcement's
own timezone -- there is never a second slot to disambiguate within a day.
The dedup key is therefore (announcement_id, local_date_str). It is checked
by comparing the LOCAL DATE of the stored `last_sent_at` (converted into the
announcement's timezone) against the local date of the slot under
consideration: if they match, the slot has already fired and is skipped.
`last_sent_at` is written through to SQLite immediately after a successful
send (before moving to the next row), so a restart mid-minute re-reads the
same persisted date on its next tick and will not re-fire a slot that
already went out -- there is no in-memory-only state a crash can lose.
(The remaining crash window -- a process dying in between a successful
`dispatch_scheduled_custom_broadcast()` call returning True and the
`UPDATE ... SET last_sent_at` write landing -- mirrors the exact same
after-dispatch-stamp pattern already used by ReminderScheduler and the
other scheduled dispatchers in this codebase; closing it fully would need a
durable pre-commit intent log, which nothing else here has either.)
Pacing
------
Reuses ReminderScheduler's `_space()` mechanism verbatim in spirit: a
shared `_last_dispatch_at` timestamp and a minimum gap between consecutive
SUCCESSFUL announcement dispatches, so N announcements eligible in the same
tick go out spaced apart rather than bursting. This is roll-call-level
pacing (announcement vs. announcement). Fan-out to the multiple channels
WITHIN one announcement is not separately throttled here -- each channel
send already goes through `RadioSendQueue`'s per-transport inter-packet
jitter at the connector layer (the same mechanism dispatch_scheduled_
fire_broadcast's multi-channel `plan` loop relies on), so a 5-target mixed
announcement is naturally paced without inventing a second mechanism.

-- v30 custom_announcements: user-crafted scheduled announcements.
--
-- Free-text broadcasts the owner types straight into the GUI ("at 08:00
-- every day, send: <literally anything>") -- NO placeholders, NO templating,
-- NO data source. Distinct from every other scheduled broadcast in this
-- codebase (band_conditions, reminders, wzdx_summary) in that it carries its
-- OWN explicit destination list (`channels`) instead of routing through a
-- toggle + region_routes matrix -- see dispatch_scheduled_custom_broadcast()
-- in notifications/pipeline/dispatcher.py.
--
-- schedule_kind determines which of the cadence columns is authoritative:
-- daily -- time_of_day only.
-- interval_days -- time_of_day + interval_days (anchored at created_at's
-- local calendar date -- see CustomAnnouncementScheduler).
-- weekly -- time_of_day + dow_mask (JSON list of 7 booleans,
-- Mon-first, i.e. index 0 = Monday .. 6 = Sunday).
-- monthly -- time_of_day + day_of_month (1-31; clamped to the last
-- day of shorter months at fire time, e.g. 31 fires on
-- Feb 28/29).
--
-- channels is a JSON list of {"transport": "meshtastic"|"meshcore",
-- "channel": <int index>|<str name>, "name": <optional display name>} --
-- UNBOUNDED length, arbitrary mix of transports, no "primary channel"
-- concept. Every entry gets its own delivery + its own mesh_broadcasts_out
-- audit row (dispatch_scheduled_custom_broadcast loops the list).
--
-- New announcements start DISABLED (enabled=0) -- the owner arms them
-- explicitly after reviewing via POST /api/announcements/{id}/preview.
-- There is deliberately NO "send now" endpoint anywhere in this feature.
--
-- last_sent_at doubles as the scheduler's restart-safe dedup marker: it is
-- stamped with the actual send epoch, and the scheduler compares the LOCAL
-- CALENDAR DATE (in `timezone`) of last_sent_at against the local date of
-- the slot under consideration -- since every schedule_kind fires at most
-- once per local calendar day, same-date == already-sent-today, and this
-- survives a restart because it is written through to SQLite immediately
-- after a successful send (see CustomAnnouncementScheduler._maybe_fire).
