Added
- Settings page — admin-only page for managing integrations and configuration
- OpenCelliD tower geolocation — LTE tab now shows cell tower coordinates (Google Maps link) and CellMapper centers on the connected tower; requires free API key from opencellid.org, configured in Settings
- SFP module diagnostics — optical Rx/Tx power, temperature, voltage, and vendor info displayed in port tooltips; Rx power shown on port badge
Fixed
- Upgrade status display (#13) — removed misleading "Upgrades Available" dashboard tile; upgrades page now shows separate "Available" and "FW pending" badges; offline devices correctly show "Offline" status
