* refactor(graphics): select Arduino_GFX panels with a capability flag
TFTDisplay tested `defined(HACKADAY_COMMUNICATOR)` in a dozen places to mean
"this panel is driven by Arduino_GFX rather than LovyanGFX". Every new
Arduino_GFX board had to be appended to all of them.
Move the decision into the variant as USE_ARDUINO_GFX so the display code
stops naming individual boards. No behaviour change: the Hackaday Communicator
is still the only board that sets it.
* feat(boards): add Heltec RC32, RC52 and RCC6
Three boards around the same 128x220 NV3001B panel: RC32 (ESP32-S3), RCC6
(ESP32-C6) and RC52 (nRF52840). They differ only in how the panel bus is
wired, so they share one branch in TFTDisplay behind TFT_NV3001B.
RC32 and RC52 also carry a rotary encoder on a TCA6408 I2C expander. That
lands as its own input source rather than as board conditionals inside
i2cButton, which is the M5Stack UnitC6L button driver and stays untouched.
On RC52 and RCC6 the panel is an add-on module, so probe it before reporting
a screen. The probe reuses the bit-banged SPI helper that already backs the
T114 ST7789 check.
Arduino_GFX is pinned to the upstream commit that added the NV3001B driver;
it has not shipped in a tagged release yet.

* feat(gps): detect and configure the LC760CA GNSS module
The LC760CA is another Unicore part, so it joins the $PDTINFO probe family
and reuses the CM121 message-rate setup. It answers with CC1161W.
GNSS_MODEL_LC760CA goes immediately before GNSS_MODEL_GENERIC_NMEA: the
sentinel has to stay last because isValidGnssModel() uses it as the exclusive
upper bound on values the probe cache may hold. Placing the new model after
it would leave LC760CA permanently uncacheable.

* fix(graphics): re-init the NV3001B after the panel rail comes back
DISPLAYOFF de-asserts VTFT_CTRL, which cuts power to the panel, so the
controller loses MADCTL, COLMOD and gamma. displayOn() only sends sleep-out
and cannot restore them, leaving the panel dark or in the wrong format after
wake. Re-run begin() once the rail has settled, and repaint in full since the
re-init leaves display RAM undefined.
Also stop the TCA6408 rotary polling from two threads at once. Registering as
an InputPollable meant InputBroker's pollSoon task could call pollOnce() while
runOnce() was mid-transfer on the main thread, with nothing serialising Wire
or the decoder state. Drop InputPollable and have the interrupt wake the
thread instead, the way ButtonThread does, so the bus and the decode stay on
one thread.
* fix(graphics): skip the NV3001B wake when re-init fails
begin() reports whether the bus came up. Ignoring it meant a failed re-init
still lit the backlight and drove a full-screen repaint at a panel that was
never initialised.
* chore(boards): ship the Heltec RC boards at release level
release is the normal level for a variant; the matrix generator still builds
each of these in this PR because they add a new platformio.ini.
