feat(ui-lvgl): roadmap stage 4 - tools grouped by context, Settings in L1 order, full status icons

- Map tools hold trail, live share and arrival alert, with their options
  (schema page "Map options") behind one button; back returns to the map
- Nearby gets an advert button: send now (nearby / everyone) + auto-advert
- Home page 3: Repeater, Admin (list of repeaters and room servers),
  Diagnostics
- Settings: display, sound, radio (Bluetooth, WiFi), system, keyboard,
  contacts & messages; units moved to Display & power
- Status bar: Bluetooth, GPS, alarm, mute, then auto-advert, trail, live
  share, repeater, arrival alert in the accent colour
- Fonts: key and route glyphs

+Env `Wio_Tracker_L2_companion_solo_lvgl_v3` (flash with `L2_ENV=Wio_Tracker_L2_companion_solo_lvgl_v3`). Bluetooth runs on NimBLE now, the speaker on the new I2S driver. Internal heap at runtime: 147.9 KB free on 3.x vs 147.8 KB on 2.0.17 (large UI buffers moved to PSRAM; static RAM 109 → 71 KB).
