The OneControl panel's command characteristic is a streaming (Write Without
Response) endpoint. Bleak 3.x changed write_gatt_char to default to
write-with-response when the char advertises the "write" property, so every
command (incl. switch turn_on/off) got rejected by the panel with ATT 0x0E
(Unlikely Error), surfaced as BleakGATTProtocolError. Force response=False on
the command write (matching the auth key write) to restore control.
Also commits the productionized custom_components integration (config flow,
coordinator, switch/sensor/cover entities, key-seed TEA auth, COBS codec) and
the matching src/ RE client/COBS fixes (big-endian framing, table-driven CRC8,
status-event decoding) that were developed but never tracked.
Verified live on the campsite HAOS Pi: switch.exterior_lights / interior_lights
toggle the physical panel with no GATT error.

Root cause of immediate disconnect after write: panel requires auth on
service 0010 before accepting commands on 0030. Protocol found by
decompiling Plugin.BLE.dll (BleDeviceUnlockManager.PerformKeySeedExchange).
Auth flow:
1. Read 4-byte seed from char 0012 (00000012-0200-a58e-e411-afe28044e62c)
2. Apply modified TEA with RV-specific cypher (612643285 / 0x248431D5)
3. Write 4-byte little-endian result to char 0013
4. Retries up to 3x if seed < 4 bytes (panel not yet ready)
connect() now calls perform_auth() before enabling 0034 notifications.
Also cleans up experimental auth attempts from campsite debugging session.

- Fix scan_for_onecontrol() to use return_adv=True and adv.service_uuids
(device.metadata removed in bleak 3.x)
- Add missing _parse_get_devices_response() — was called but never defined,
would crash on first real device response
- main() now auto-connects when exactly one device is found via scan
- Remove premature turn_on/off_light(5) calls from main() — device IDs
unknown until get_devices() has been run against real hardware
- Guard send_command() and disconnect() against unconnected state
- control_awning() now takes MovementState enum instead of raw int
- Bump post-get_devices sleep from 2s to 5s for real device latency
