feat(ui-lvgl): power saving, review fixes, shared helpers

Browse Source 
Power: the UI loop sleeps until something is due (never with packets
queued); screen off puts the CPU at 80 MHz, the GT911 to sleep (unless a
tap wakes the screen) and the LP5814 in standby. GPS off now cuts the
L76K's rail and UART on the L2 (L2GpsProvider). The battery divider is
powered only for a reading (measured: settles at once); readings within
2 s are reused. The SD mount is retried at most every 5 s.

Fixes: WiFi left on after leaving a scan, live tiles' WiFi kept with the
screen off on the map, an ADC read every second for the status bar, touch
polled on every pass while dark, a scan cutting an update's WiFi, relay
count not refreshing in a channel thread, raw @[nick] in room previews.
Labels skip unchanged text (no redraw).

Helpers: scrollList, dimOverlay, settingRow, flexBox, nvs::get/put,
trailFilePath (a second save in the same minute no longer overwrites),
unreadTotal. Dead code removed.
