efiten 317b59ab10 feat: area-based visual node filter — attribute packets by transmitter GPS (#804) (#839)
## Summary

- Adds configurable GPS polygon areas to `config.json`; nodes are
attributed to an area if their last-known position falls inside the
polygon
- New `Area: …` dropdown filter (matching the existing region filter
style) appears on all analytics, nodes, packets, map, and live screens
when areas are configured
- Backend resolves area membership with a 30s TTL cache; area filter
bypasses the 500-node cap on `/api/bulk-health` so all area nodes are
always returned
- Includes a polygon builder tool (`/area-map.html`) for drawing and
exporting area boundaries

## Changes

**Backend**
- `AreaEntry` type + `Areas` config field
- `GetNodePubkeysInArea` DB query + `resolveAreaNodes` (30s TTL,
`areaNodeMu` RWMutex)
- `PacketQuery.Area` + `filterPackets` polygon check
- `?area=` param propagated through all analytics, topology,
clock-health, and bulk-health routes
- `/api/config/areas` endpoint

**Frontend**
- `area-filter.js`: single-select dropdown, persists to localStorage,
cleans up stale keys on load
- Wired into analytics, nodes, packets, channels, map, and live pages
- Live map clears node markers on area change

**Docs & tools**
- `docs/user-guide/area-filter.md` — configuration and usage guide
- `docs/api-spec.md` — updated with new endpoint and `?area=` param
table
- `tools/area-map.html` — polygon builder for defining area boundaries
- Demo areas added to `config.example.json`

## Test plan

- [x] No areas configured → filter dropdown does not appear on any page
- [x] Areas configured → dropdown appears, "All" selected by default
- [x] Selecting an area filters nodes/packets/topology/map correctly
- [x] Selecting "All" restores unfiltered view
- [x] Selection persists across page reloads (localStorage)
- [x] Stale localStorage key (area removed from config) is cleared on
load
- [x] `/api/bulk-health?area=X` returns all nodes in area (no 500-node
cap)
- [x] `/api/config/areas` returns correct list

# Nodes
The Nodes page lists every node your mesh has seen — repeaters, companions, rooms, and sensors.
[Screenshot: nodes list with status indicators]
## What you see
Each row shows:
- **Name** — the node's advertised name (or public key if unnamed)
- **Role** — Repeater, Companion, Room, or Sensor
- **Status** — color-coded health indicator
- **Last seen** — when the node was last heard
- **Advert count** — how many advertisements this node has sent
## Status indicators
| Indicator | Meaning |
|-----------|---------|
| 🟢 Active | Heard recently (within threshold for its role) |
| 🟡 Degraded | Not heard for a while but not yet silent |
| 🔴 Silent | Not heard for an extended period |
Thresholds differ by role. Infrastructure nodes (repeaters, rooms) have longer grace periods than companions. See [Configuration](configuration.md) for `healthThresholds`.
## Filtering
### Role tabs
Click **All**, **Repeaters**, **Rooms**, **Companions**, or **Sensors** to filter by role.
### Search
Type in the search box to filter by name or public key. The filter applies instantly.
### Status filter
Filter to show only active, degraded, or silent nodes.
### Area filter
If [areas are configured](area-filter.md), an area pill bar appears above the list. Selecting an area shows only nodes whose GPS position falls within that area.
### Last heard filter
Filter nodes by how recently they were heard (e.g., last hour, last 24h).
## Sorting
Click any column header to sort. Click again to reverse the order. Your sort preference is saved across sessions.
## Node detail
Click a node row to open the **detail pane** on the right. It shows:
- Full public key
- Role and status explanation
- Location (if known)
- Recent packets involving this node
- Neighbor nodes
- Signal statistics
Click the node name in the detail pane to open the **full node page** with complete history, analytics, and health data.
## Favorites
Nodes you've claimed on the Home page appear as favorites. You can also star nodes directly from the Nodes page.
## Tips
- Use the search box for quick lookups — it matches partial names and keys
- Sort by "Last seen" descending to find the most active nodes
- The status explanation tells you exactly why a node is marked degraded or silent
