PR #5 of the v0.7.x GUI rework arc. Production code; central-gui restart only
(supervisor untouched -- data_class is read only by central-gui per request).
- SourceAdapter gains a `data_class` class attr (Literal["event","telemetry"],
default "event"). NWIS opts in as "telemetry" (continuous high-volume water
gauges); every other adapter stays "event". The /events vs /telemetry split is
thus registry-derived from class attrs -- no hardcoded adapter-name lists.
- routes.py refactor: `_class_adapter_names(data_class)` and a `data_class` arg
on `_adapter_filter_options` scope the flat + domain-grouped chip/legend lists
to a class (colors stay keyed to the FULL registry, so an adapter keeps one
color across tabs). `_fetch_events` accepts `class_adapters` and adds an
`adapter = ANY(...)` condition. Shared `_events_query`, `_events_page(data_class,
base_path)` and `_events_rows_fragment(...)` back both tabs; `/events`,
`/events/rows`, `/telemetry`, `/telemetry/rows` are thin wrappers.
- Templates parameterized with a `base_path` context var (form action, hx-get,
hx-push-url header, clear-all redirect, JS BASE_PATH const); the `_events_rows`
paginator macro takes `base`. Same templates serve both tabs; nav gains a
Telemetry link.
- /events.json UNCHANGED -- the cursor path sets no `class_adapters`, so the
subject + pagination contract is intact (TestEventsJsonSubject still passes).
Adds TestTelemetrySeparation (data_class defaults, registry split 11 event / 1
telemetry, class-scoped filter options, color stability, and the `adapter =
ANY(...)` SQL shape incl. the no-class events.json path). Updates the events
frontend tests for the base_path-parameterized templates.
Full suite: 682 passed, 1 skipped (central and unprivileged zvx, 3x each).
