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 Ikoka boards are based on the Xioa NRF52840 module which is known
to have the LC circuit for the internal DC/DC regulator to be
available. Enable it to save power.
