docs(v0.7): comprehensive dashboard docs rewrite -- Reference +8 sections, per-page tooltips, component polish

All three approved tiers in one commit. Reference.tsx is the deep docs
hub (8 new sections); the 10 other pages get short helper text +
tooltips that cross-reference back into Reference; 3 components get
operational-context tooltips. No new features land here -- this is the
copy that catches the GUI up to v0.6 + v0.7 system behavior.

Decisions applied per Matt's call:
- Keep both bang commands AND the LLM DM path (bangs are short on a
  mesh-constrained interface; LLM is the anything-else path). Cross-
  references between the two land in Reference -> Commands and
  Reference -> LLM DM Queries.
- Rename "wire-string rendering" to "broadcast text" in user-facing
  copy on TownAnchors.tsx, GaugeSites.tsx, and the Curation section of
  Reference.tsx.
- Keep the "AND-model anti-pattern" tooltip as-is on Environment.tsx +
  GaugeSites.tsx (specificity is the value for advanced users); the
  OR-not-AND Reference section is its home definition that other
  tooltips can link to.

Ham terminology preserved:
- Reference.tsx solar/Kp section retains "Quiet sun" / "Quiet HF
  conditions" language (SFI/Kp vocabulary, not the deleted Quiet Hours
  feature -- confirmed via direct grep before writing).

Tier 1: Reference.tsx (the depth doc) -- 8 new sections, ordered for
readability:

- "Fire Tracker (Fusion)": Phases 1-4 unified. Six fire-family alert
  categories with example wire strings (wildfire_declared,
  wildfire_growth, wildfire_halted, wildfire_spotting,
  unattributed_hotspot_cluster, wildfire_incident). Attribution
  mechanics (spread_radius_mi default, centroid as 24h median).
  Movement mechanics (pass_id bucketing, per-pass centroid, 8-way
  bearing, mi/h drift). Spotting mechanics (convex-hull perimeter +
  vertex-distance approximation + per-fire cooldown). Daily LLM digest
  (twice-daily summary broadcaster). The 10 fires.* adapter_config
  knobs with defaults.
- "Broadcast Types": the three prefix categories -- New: (first sight),
  Update: (material change), Active: (clock-driven reminder).
- "Reminder System": cadences per adapter (WFIGS 8h, SWPC 8h, ITD 511
  per-zone). The tombstone (fires.tombstoned_at) termination. The
  per-adapter reminder_enabled flag.
- "LLM DM (Natural-Language Queries)": all 7 env_reporter adapter
  blocks (build_fires_detail / build_alerts_detail / build_quakes_detail
  / build_traffic_detail / build_gauges_detail / build_swpc_detail /
  build_drop_audit) with example questions that hit each one. The
  grounding clause behavior ("No active X right now" when an adapter
  block is empty -- the v0.7-fire-tracker-4-final clamp). The
  include_in_llm_context per-adapter toggle.
- "OR-not-AND Architecture": the per-adapter Central vs native
  contract. Mutually exclusive. The AND-mode anti-pattern definition
  (referenced by the Environment + GaugeSites tooltips). The Spokane
  fix context.
- "Adapter Config & the CODE Rule": the GUI knob hub. The CONFIG-vs-
  CODE split (thresholds in CONFIG, sentence templates / emoji /
  translation maps in CODE). Restart-required vs live keys. The
  include_in_llm_context toggle.
- "Curation: Gauges & Towns": Gauge Sites (NWS-AHPS thresholds, USGS
  lookup, Action/Minor/Moderate/Major). Town Anchors (broadcast text
  suffix lookup chain: Photon -> this table -> landclass -> county
  -> coords). Example output "3 mi N of Almo".
- "Schema Migrations": light touch. v11-v16 schema additions tagged
  with the phase they shipped under.

Tier 2: per-page tooltips and cross-references (10 pages):

- AdapterConfig.tsx: header paragraph extended with the CODE rule
  pointer + LLM context toggle explanation.
- Alerts.tsx: !subscribe blurb extended with the three broadcast types
  and links to Reference -> Broadcast Types + Reminder System.
- Config.tsx: environmental section description updated to point at
  Environment.tsx for adapter knobs + Reference -> OR-not-AND for the
  architecture.
- Dashboard.tsx: RF Propagation title carries SWPC R/S/G + Kp legend
  tooltip; LOCAL badge defines what counts as local.
- Environment.tsx: Central region-token helper now references the
  OR-not-AND section; tick_seconds defined inline as the native-mode
  poll interval.
- GaugeSites.tsx: page description rewritten -- replaces "envelope
  time" jargon with operational language, explains USGS lookup
  mechanics, points at Reference -> OR-not-AND for the central-feed
  disable.
- Mesh.tsx: Topology + Geographic buttons get tooltips defining the
  rendering model.
- Notifications.tsx: band-conditions block extended with the daily
  fire digest pointer + Reference -> Fire Tracker + Broadcast Types
  cross-refs.
- TownAnchors.tsx: page description rewritten -- "wire-string
  rendering" -> "broadcast text", chain fallback explained ("Photon
  -> this table -> landclass -> county/state -> coords"), example
  output included.

Tier 3: component tooltip polish (3 components):

- NodeTable.tsx: Battery + Last Heard column headers get title-bearing
  spans with the voltage chart + offline-threshold legend.
- NodeDetail.tsx: SNR quality bands documented as a comment in the
  neighbor render block (the legend lives next to where the colored
  quality dots are computed).
- RestartBanner.tsx: banner copy extended with the restart-required
  catalog (Config -> environmental, LLM backend swap, dispatcher
  cold-start grace) so operators know what touched it.

Build verification:
- tsc + vite build green (one warning about chunk size > 500kB --
  pre-existing).
- All 8 new TOPICS ids resolve in the served bundle:
    adapter-config, broadcast-types, curation, fire-tracker,
    llm-dm, or-not-and, reminders, schema.
- Distinctive new strings present in the bundle ("3 mi N of Almo",
  "Photon nearest-town", "AND-mode anti-pattern", "R (Radio Blackouts").
- "Quiet sun" preserved (the ham SFI/Kp vocabulary in the Solar
  section, not the deleted Quiet Hours feature).
- Container Up healthy, 0 tracebacks in 2 min post-rebuild.

Changelog: v0.7-docs-rewrite.md (per-page strip / rewrite / add table).
