feat: Support Elecrow ThinkNode M9 (#10908)

* thinknode-m9 variant

* move lora to SPI1 device

* enable SDcard

* use HSPI

* BaseUI tft -> HSPI

* buzzer, webdav lib

* fix build issues

* M9 default to MUI, no BT, short ringtone

* add keyboard long-press config

* update variant

* add ThingNode-M9 GPS string

* GPS 115200 baud

* Basic BaseUI support

* Fixup power detection

* Compass and KB fixes for M9

* add timed Lock::lock()

* add SD card

* point device-ui to thinknode m9 draft branch

* trunk fmt

* fix FusionCompass

* Fix t-deck-tft linker arg list overflow in CI

* SDcard/lora fix: SPI1 must not be declared twice in arduino 3.x -> reuse SPI1 defined in FSCommon.cpp

* update battery parameters

* reinit SD card when updating; fix PSRAM size

* update lib versions

* fix wakeup on key press (KB_INT)

* fix default nag_timeout for TFT/MUI devices with buzzer

* increase PSRAM and SD freq

* trunk fmt

* update lovyanGFX 1.2.26

* update device-ui commit reference

* fix screen definition

* remove DONE; maybe a keyword or other used identifier

* fixed CI error nag_timeout

* fix prepareSleep initialization

* trunk fmt

* reduce SD SPI frequency

* update device-ui

* fix SDcard issue

* stage

* fix device-ui commit reference

* fix device-ui commit

* update device-ui commit (fixed keyboard lag)

* fix QMI8658

* trunk fmt

* update .ini meta information, align SD freq

* fix device-ui reference to target (ready to merge)

* device-ui for all other targets

* make the rabbit happy

* trunk fmt

* fixed lock screen

* fix compile error

* SPI lock timeout

* apply device-ui fix

* revert bad RadioLib commit hash in platformio.ini
