feat(l1): Home quick panels, map page with live data, quieter status bar

- Icon pages become quick panels: two or three rows (Settings, Messages,
  Bluetooth, Advert, Tools, Power) inset from the edges, the last one
  opening the full screen. Brightness and auto-advert are edited in place
  (Enter, Left/Right, Enter/Back saves once).
- Tools panel shows the two tools used last with their live state.
- Map page: preview on the left, GPS / trail / live / target on the right.
- Favourites as soft cards; Status tile with a battery spark line.
- Status bar without boxes or blinking; BT only when connected, GPS
  search glyph without a fix.
- Redrawn mini icons (advert waves, cog, wrench, messages); big hovering
  icons removed. Tools list is text only.
