feat: implement passive radar auto-detection of router AP

Automatically detect the home router as a passive radar TX source,
eliminating need for a dedicated active TX node.

Firmware changes:
- During hello message, include ap_bssid and ap_channel from esp_wifi_sta_get_ap_info()

Mothership changes:
- On hello: extract ap_bssid; if >=80% of nodes report same BSSID create virtual node entry with virtual=1
- OUI lookup: embedded IEEE OUI registry as Go map compiled via go:embed; display router brand
- Detect AP BSSID change (router reboot/replacement) and emit system alert
- SQLite nodes table: add virtual BOOL, node_type TEXT, ap_bssid TEXT, ap_channel INT columns

Dashboard changes:
- Show "I detected your router (ASUS). Place it on the floor plan..." notification
- Render virtual AP nodes with distinct router icon in 3D view
- Drag-to-place virtual node (distinct router icon) in 3D editor
