thinknode_m8: initial support
adds some functionalities to ui_task and epddisplay:
epd display,
- supports screen off, and clear screen
- supports forcing full refresh every N partial refreshes (off by default, configured to 60 for M8)
ui_task
- UI_SHOW_CLOCK flag to display clock on first screen
- rotary button can act like joystick (with regards to Enter key), defaults to old config for existing nodes
- screen off on long press when using rotary button (very handy for the watch)
The contact sync streams up to MAX_CONTACTS frames back to back, but
ArduinoSerialInterface never checked whether the stream could take
them: isWriteBusy() returned false unconditionally, so MyMesh's pacing
gate had no effect, and writeFrame() called write() without looking at
availableForWrite(). On ESP32 (HWCDC, 256 byte TX ring) a host that
stalls for a moment makes the driver drop queued bytes silently, which
tears a frame in half - and since the framing is length prefixed with
no checksum and no resync marker, the client stays desynchronised for
the rest of the session. Reported as 'the app disconnects while
syncing contacts' on devices with a large contact list.
Add opt-in flow control: report busy until a whole frame fits, and
drop frames as a unit instead of tearing them. Enable it for the
companion USB interface and give HWCDC a bigger TX buffer with a short
write timeout, mirroring what kiss_modem already does.

ArduinoSerialInterface::isConnected() always returned true, so any
companion build with a USB interface believes a client is attached from
boot onwards. Two user visible effects:
- new message notifications never fire, because MyMesh only notifies
the UI (display, buzzer) while no client is connected
- on builds that also expose BLE the home screen shows '< Connected >'
instead of the BLE pairing PIN, so a freshly flashed device cannot be
paired at all
Add an optional connection check callback and wire it up per platform:
native USB-CDC (TinyUSB on nRF52/RP2040/ESP32 with USB_MODE=0) exposes
real DTR through (bool)Serial. The ESP32 USB-Serial-JTAG peripheral has
no DTR concept - it reports 'connected' as soon as the host enumerated
the device - so fall back to frame activity there. Plain UARTs keep the
previous assume-connected behaviour.

Picks up upstream MeshCore 1.17.1.
Notable upstream content:
- 1.17.1 version/build-date bump in the example MyMesh headers.
- nRF52: combine radio entropy with CC310 RNG.
- Companion FEM prefs: load/save of fem_ properties commented out until they
can be set from the client.
- Scoped reply routing: replies no longer dropped when flood.max.unscoped is
low (RoutingPolicy + unit tests).
- nRF52 unused-pin sweep (T1, T-Echo Lite, MeshPocket).
No conflicts.
