perf(ui-lvgl): lower clock when idle, fewer redraws, wake on BLE frames

- CPU at 80 MHz with the screen on after 2 s without touch or animation;
  a touch restores the full clock before its frame is drawn
- setText(): periodic refreshes no longer redraw unchanged labels
  (status bar, Home, lock, Diag, GPS, compass, clock, map, nav, nearby)
- map markers kept across the 3 s rebuild when unchanged
- app connected: the loop blocks until a BLE frame arrives
  (serialFrameArrived / hasPendingFrames) instead of polling every 2 ms
- PSRAM: boot frame sprite and the HTTP response buffer released
