Resolve conflict in variants/heltec_v4/platformio.ini by taking
origin/dev version for PA pin comments and SX126X_RX_BOOSTED_GAIN.

- Implemented PSRAM availability checks and logging to assist in debugging memory fragmentation on boards with external RAM.
- Enhanced logging to provide detailed information about PSRAM size, free memory, and initialization status.
- Updated platformio.ini files across multiple variants to remove obsolete mbedTLS configuration flags, streamlining the build process.
- Added new build flags for mbedTLS: CONFIG_MBEDTLS_ASYMMETRIC_CONTENT_LEN, CONFIG_MBEDTLS_SSL_IN_CONTENT_LEN, and CONFIG_MBEDTLS_SSL_OUT_CONTENT_LEN.
- These changes improve the handling of SSL content lengths, optimizing performance for various hardware variants.
- Updated source filters to include MQTTBridge and MQTTMessageBuilder in relevant configurations.
- Added memory debugging features to log heap usage and fragmentation recovery for MQTT clients.
- Introduced `recreateMqttClientsForFragmentationRecovery()` to manage MQTT client lifecycles and reduce memory fragmentation.
- Updated critical memory checks to log detailed heap statistics and active MQTT client counts.
- Included new debug logging for memory status every 60 seconds when memory debugging is enabled.
This update aims to improve stability and performance in memory-constrained environments.
- Trigger noise floor calibration every 2s and AGC reset every 30s in main loop.
- Reorder loop to match Dispatcher: calibrate + radio.loop() before AGC reset
and recvRaw() so RSSI is never sampled right after startReceive().
- Update protocol doc with calibration intervals and typical noise floor range.
- Variant platformio.ini updates (heltec_v3, rak4631).
When DISPLAY_CLASS is defined via build flags but HELTEC_LORA_V4_OLED
or HELTEC_LORA_V4_TFT flags aren't set, include SSD1306Display.h as
fallback. This fixes compilation errors for environments like
heltec_v4_repeater_observer_mqtt that extend Heltec_lora32_v4 directly
and set DISPLAY_CLASS=SSD1306Display.
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
