v0.2.0

Fix Unsupported warnings and OTA rollback race

- Remove set_whitebal, set_awb_gain, set_gain_ctrl from apply_camera_settings():
  all three are wired to set_dummy in mega_ccm.c (W mega_ccm: Unsupported noise)
- Remove now-unused CAM_AWB and CAM_AGC defines
- ota_mgr_run_pending(): call recovery_mgr_signal_planned_reboot() before the
  OTA-complete esp_restart() so the new firmware boots with boot_count=0;
  previously two crashes post-OTA would trip the boot-loop threshold
