## Summary
Hide RF link-related UI elements from the network map page while keeping all backend code intact.
### Changes
- Commented out "View RF Links" button in network map node detail panel
- Commented out RF Link health legend (Good signal / Degraded / Critical) from map legend
- Backend topology.ex code untouched — `compute_rf_link_stats/1` and `enrich_edges_with_rf/2` remain
- No RF tab exists on the device show page, so no changes needed there
### Verification
- `mix compile --warnings-as-errors` — zero warnings
- `mix test` — 8490 tests pass, 0 failures
Paperclip issue: TOW-44
Reviewed-on: graham/towerops-web#45
The StormDetector was being added twice:
1. In the main children list (line 127)
2. In background_workers() (line 176)
This caused the supervisor to fail with 'duplicate_child_name' error.
Removed the duplicate from main children list since it's correctly
placed in background_workers() which also handles test env properly.
- Tower/device icons: role-based shapes (triangle for APs/wireless,
diamond for switches, round-rect for routers, hexagon for firewalls)
- RF link overlays: edges colored by signal health (green/yellow/red)
with bandwidth-proportional line thickness
- Enhanced hover tooltips: device-to-device name, SNR dB, bandwidth,
signal health indicator
- Wireless client count badge on AP nodes
- Filter bar: All Links | Degraded Only | Sites with Alerts | Search
- Search with zoom-to-match and highlight
- Geographic layout toggle (when sites have lat/lng)
- Enhanced detail panel: RF stats (client count, signal health, SNR),
View RF Links button for wireless devices
- Backend: compute_wireless_stats/compute_rf_link_stats enrich topology
- Site nodes include lat/lng for geographic layout
- Edge enrichment with RF signal health from SNR sensors
- Fix pre-existing compile error in notification_rate_limiter.ex
- fix bidirectional link queries to find links where device is source or target
- merge A→B and B→A edges into single link with combined confidence
- include interface speed in edge data for variable edge width
- infer discovered node roles from LLDP/CDP capabilities (router, switch, wireless, phone)
- store remote_capabilities in link metadata during evidence processing
- replace Cytoscape destroy-and-recreate with element diffing to preserve zoom/pan/positions
- add node detail slide-out panel with device info, connections, and confidence
- support ?node= URL param for deep-linking to selected nodes
- add site-based compound node grouping in Cytoscape
Build a rich network topology from SNMP polling data using evidence-based
confidence scoring. LLDP/CDP neighbors, MAC address tables, and ARP data
are combined to infer device links with weighted confidence merging.
- Add DeviceLink and DeviceLinkEvidence schemas for persistent topology
- Implement evidence collectors: LLDP (0.95), CDP (0.95), MAC (0.7), ARP (0.6)
- Add device role inference from sysObjectID/sysDescr patterns
- Hook topology inference into DevicePollerWorker pipeline
- Add stale link cleanup (24h mark stale, 72h delete) via NeighborCleanupWorker
- Update NetworkMapLive with "Added" vs "All Devices" tabs
- Add connected devices section to device detail page
- Add device role selector to device edit form
- Update Cytoscape.js with role-based node shapes/colors and confidence edges
green for online, yellow for unknown, red for offline. previously
nodes were colored by device type which didn't convey health state.
also remove agent last_seen_at display from device detail page since
the offline badge already communicates agent health.
