The screen faded as the device was used: text went grey a few updates
after it was drawn, while whatever had just changed stayed crisp. Only a
full refresh brought it back, and the next few updates ate it again.
A partial update is differential -- the controller drives only the pixels
that differ between its "current" (0x24) and "previous" (0x26) RAM and
leaves the rest to hold their own charge, which this panel doesn't do
well. Priming the previous-image RAM with the inverse of the incoming
frame makes every pixel a difference, so all of them get driven to their
target, in both directions.
The inverse matters: priming with flat white makes only white->black a
difference, so ink is re-driven but never erased and every screen ever
shown accumulates as a ghost. Confirmed on hardware, both ways round.
Costs one extra full-screen RAM write (a few ms of SPI). The refresh
itself is unchanged -- the waveform clocks the whole panel regardless of
how many pixels it drives -- so nothing got slower. Clearing ghosts is
still the periodic full refresh's job (Settings > Full rfsh), which can
now stay off.
The helper needs GxEPD2_BW's private _buffer/_page_height, so it goes in
the patched copy of the header, which every e-ink build now includes
unconditionally rather than only screenshot-enabled ones. All e-ink
variants pin GxEPD2 1.6.2, the version that copy tracks.

A message containing a line break drew two words on top of each other in
the fullscreen reader. wrapLines() treated '\n' as an ordinary character:
it measured it via getCodepointWidth() -- which reports a full 6px cell
for it, since 0x0A sits below the font's first glyph -- and copied it into
the wrapped line. Both display drivers' print() then acts on '\n' by
resetting the cursor to x=0 and stepping down one row, so the tail of that
line was drawn straight over the following one.
wrapLines() now ends the line at '\n'/'\r' (CRLF counts as one break) and
consumes the byte rather than emitting it, preserving blank lines the
sender typed while still skipping degenerate empty wrap segments so the
loop can't stall. This covers the fullscreen view and the history list's
portrait bubbles, which share the function.
drawTextEllipsized() folds newlines into spaces for the same reason: it
draws one line clipped to max_width, and the compact one-line message
previews in the landscape list feed it raw message bodies. A space keeps
the words apart and measures the same, so the ellipsis maths is unchanged;
for names and labels it's a no-op.

If Bluefruit.begin fails, BLE OTA mode won't actually start and the board might require a reboot to reattempt.
Fixes:
- Bluefruit.begin returns false in NRF52Board.startOTAUpdate if OTA mode fails to start. User is notified of the fault through existing error message in CommonCLI and can reattempt "start ota" command.
Satellite count alone is a poor proxy for fix quality -- few satellites
in good geometry can beat many in poor geometry. LocationProvider now
exposes getHDOP() (default -1 = unsupported); MicroNMEA implements it.
isLocFixReady() prefers HDOP <= 2.0 when available, falling back to the
old >=8 satellite threshold for providers that don't report it (e.g.
RAK12500/u-blox).

Auto-detected at boot on Wire1/Grove (addr 0x5F) -- no setting to flip, and a
no-op on boards without that bus or with nothing attached. This UI's key
codes (KEY_LEFT/UP/DOWN/RIGHT/ENTER/CANCEL) already match CardKB's own byte
protocol, so most input needs zero translation and flows through the same
key queue as physical buttons.
Two bytes get remapped in UITask::pollCardKB():
- Enter, only when the on-screen keyboard's plain grid state is active (no
placeholder/accent popup, not in cursor-mode), becomes a new KEY_KB_ENTER
sentinel meaning "submit the field" -- reusing plain KEY_ENTER there would
insert a stray character, since a CardKB typist's row/col never reflect an
intentional grid selection. Everywhere else Enter is untouched, so
selecting a placeholder or committing an accent still works normally.
- Tab (otherwise unused) becomes KEY_CONTEXT_MENU, standing in for the
"Hold-Enter" long-press gesture CardKB has no way to produce -- without it,
~30 context menus across the UI (message reply/navigate, Bot/Admin/
Repeater, ...) would be unreachable from the keyboard alone.
KeyboardWidget gains a direct-typing path: printable ASCII inserts straight
at the cursor bypassing the grid, Backspace deletes, KEY_KB_ENTER submits.
Build-verified: WioTrackerL1_companion_solo_dual and
WioTrackerL1Eink_companion_solo_dual both compile and link clean; also
smoke-tested Heltec_mesh_solar_companion_radio_ble (no ENV_PIN_SDA/SCL) to
confirm zero regression on boards without the feature.

SerialEthernetInterface.cpp is compiled for every nRF52 target because
PlatformIO builds all .cpp files under src/. It includes
SerialEthernetInterface.h, which unconditionally pulls in
<RAK13800_W5100S.h> -- a library only present in the RAK4631 Ethernet
env's lib_deps. As a result any other nRF52 board (e.g. Heltec T114)
fails to build with 'RAK13800_W5100S.h: No such file or directory'.
Wrap the contents of both files in '#ifdef ETHERNET_ENABLED' so they
compile to empty translation units on non-Ethernet builds. RAK4631
Ethernet envs define ETHERNET_ENABLED and are unaffected.
Fixes#2985
Improvements:
- Add condition to only turn off display if on (avoids wedging the shutdown on some displays)
- Reset LoRa radio before calling radio_driver.powerOff() to ensure it is in a known good state (and will accept the command)
- Ensure SPI is started so LoRa radio commands can be sent (some shutdowns can happen before this)
- Add gate for P_LORA_NSS pin defined before writing to the pin
