The LoRa noise floor with the board's parts off one at a time, sweeps of
850-930 MHz, the mesh channel and a 7.8 kHz zoom on its loudest point; a
slow cycle of the same states for a second radio beside the device; and
a spike hunt over 864-876 MHz listing the lines over the floor and their
spacing (how the I2S MCLK comb was found).

Shared infoCard/infoRow/infoNote helpers: muted label left, value right,
hairlines between rows, empty rows hidden. Diagnostics grouped into
sections with a received/sent packet table; GPS gets a position card and
constellation pills; About, OTA, Storage and map popups use the same
cards. Text no longer breaks after '.', clock alarm hint unclipped.
Sim-only sim_open() hook for jumping to a screen.

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.

- The AW35615 USB-C controller (FUSB302-style registers, ID 0x91) only
reports VBUSOK with its measure block on; POWER resets to bandgap only,
so isExternalPowered() was always false. Board init turns it on
- Status bar shows a charge bolt on the cable, Diagnostics > Live has a
Power row, the GPS screen notes that charging disturbs GPS, and the
low-battery warning is skipped on USB as intended
- Roadmap: USB detection closed; GPS indoors still worse than the L1
even on battery, left open for later

- Message history archived per conversation on the SD card (HIST_ARCHIVE):
restored on boot, Older/Newer paging in threads, kept count selectable
- Settings > System > Storage: card and flash usage, breakdown by maps,
messages, trails and other, kept-per-chat setting, delete history;
reads the mounted volume and warns when the FAT partition is much
smaller than the card
- Saved trails on the card: every Save is a new file, Load opens a list
with load (framed on the map), GPX export and delete
- Diagnostics: GPS data rows, last start reason, last crash summary
- Messages restored before the clock is set show their date instead of 0s
