 3. - [ ] OTA rollback via consecutive-reset counter
    - [ ] Add `RTC_DATA_ATTR uint8_t reset_counter` — increment on boot, clear after successful health check
    - [ ] On counter ≥ 5, call `esp_ota_mark_app_invalid_rollback_and_reboot()`

 4. - [ ] Critical init failures (ADC, storage, log, I2C, FSM, sensors) should `esp_restart()` — this feeds the OTA rollback reset counter
 5. - [ ] Non-critical init failures (wifi, webserver, RF, BT) should log a `LOG_TYPE_ERROR` entry and attempt retry
    - [ ] WiFi/BT already have restart paths (`webserver_restart_wifi()`, `bt_hid_resume()`) — wire these into a retry-on-failure path at boot, not just soft idle exit
-6. - [ ] Power-on self-test (POST) — run after all inits, before FSM starts; log results; feed OTA health check

+6. - [ ] Power-on self-test (POST) — run as a part of all inits. Calling init should result in a 3-try effort to do the init if there are issues, then reset.
