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
Added NRF52840 power management core functionality:
- Boot‑voltage lockout
- Initial support for shutdown/reset reason storage and capture (via RESETREAS/GPREGRET2)
- LPCOMP wake (for voltage-driven shutdowns)
- VBUS wake (for voltage-driven shutdowns)
- Per-board shutdown handler for board-specific tasks
- Exposed CLI queries for power‑management status in CommonCLI.cpp
- Added documentation in docs/nrf52_power_management.md.
- Enabled power management support in Xiao nRF52840, RAK4631, Heltec T114 boards
As all NRF52 boards now have OTA support, let's remove the subclass
and integrate it into the base class.

The startOTAUpdate() is the same for all NRF52 boards. Use a common
implementation for all boards that currently have a specific
implementation.
The following boards currently have an empty startOTAUpdate() for
whatever reasons and therefore are not inheriting NRF52BoardOTA to
keep the same state: Nano G2 Ultra, Seeed SenseCAP T1000-E,
Wio WM1110.

Some NRF52 boards are able to use the internal power-efficient DC/DC
regulator. Add a new class that can be inherited by board classes to
enable this feature and reduce the power consumption.
