Dim LED ring, add blink mode, and signal OTA outcome on the ring.

Browse Source 
Default brightness is ~5%; UART blink mode and green/red pulses mark OTA success or failure. Failed UART uploads skip ESP-NOW distribution.

`OTA_END` can take a long time on the wire (slave flash + ESP-NOW); the host should use a generous read timeout.
During OTA the LED ring shows progress at ~5 % brightness: **blue** while the image is written (UART on master, ESP-NOW on slaves), **green** on the master while it forwards the image to slaves over ESP-NOW. On **success** the ring gives one short **green** blink; on **failure** one **red** blink and ESP-NOW distribution is not started (failed UART upload / `OTA_END` validation).
`OTA_START_ESPNOW` (type `20`): re-run ESP-NOW distribution from the last staged image without a new UART upload (no-op if nothing staged).
Implementation: `ota_uart.c` (4 KiB buffer, `esp_ota_write`), `ota_espnow.c`, `cmd_ota.c`.
