agessaman 612c52132c merge: upstream/dev into observer-firmware-dev (2026-07-30, db232808)
Absorbs 106 upstream commits. Seven files conflicted; the substantive one
was upstream's new JSON ConfigSerializer (PR #2982), which replaces the
binary /com_prefs layout with /prefs.json and makes NodePrefs a
ConfigSerializer subclass.

Prefs migration
- Adopt upstream's ConfigSerializer. writeCommonPrefsImage() and its
  documented offsets (0-294) are deleted, along with the now-unreachable
  saveCommonPrefsImageAtomically()/CommonPrefsFileStore atomic rename path.
- Load order is /prefs.json, then /com_prefs, then /node_prefs. Upstream
  dropped the /node_prefs fallback; it is restored here so devices that
  never advanced past that filename keep their config.
- Legacy files are never removed, so migration cannot destroy its own
  source and a deferred or failed save simply retries next boot.
- /com_prefs is treated as a format migration only, not an "upgrade", so
  it does not trip the bridge.source tx->rx flip on existing nodes.
- The MQTTPrefsAtomicStore legacy gate is retained: the observer tail
  recovered from an old-format file still commits to /mqtt_prefs before
  /prefs.json is written.
- MQTTPrefs and /mqtt_prefs are untouched; savePrefs keeps its save_mqtt
  parameter and now returns upstream's bool.

Fixes to upstream code
- RadioPrefs::structure() bound both "rxgain" and "fem_rxgain" to
  rx_boosted_gain, so radio_fem_rxgain was never persisted. Bound to the
  correct field.
- discovery_mod_timestamp was dropped from structure(); it gates
  'since'-filtered DISCOVER replies and is set on every config change, so
  losing it would silently stop discovery responses after a reboot. Added
  as "disc_mod".

Merge artifacts repaired
- Restored bblanchon/ArduinoJson to the native test env; a clean but wrong
  auto-merge at the lib_deps block boundary dropped it and broke all 19
  host test suites.
- Migrated the fork's WebConfig UITask screens off the removed
  DisplayDriver::Color enum to upstream's UIColor element types.
- Removed duplicate getCADEnabled() definitions in companion MyMesh.cpp
  and simple_sensor SensorMesh.cpp that both sides had added.
- Dropped memset(&_prefs, 0, ...) in the four example meshes; NodePrefs now
  has a vtable. guard gains an initializer that memset used to provide.

Other resolutions
- simple_room_server keeps both the fork's discover.* commands and
  upstream's new room.post.
- docs/payloads.md taken from upstream, undoing content earlier merges had
  reverted (Control data section, split login tables).

Verified: 273/273 host tests pass across native and native_kiss_modem;
Heltec v3 repeater, repeater_observer_mqtt, room_server_observer_mqtt,
sensor, and companion_radio_ble all build clean.
