The alarm station byte is shared and follows the current radio station, so
remove the per-alarm control. Remove the FM sound option, as writing it just
turns on the radio mode. Record how the MCU treats each DP127 byte.

Prefer Home Assistant time with public NTP as fallback. Add next and previous
station, ESPHome and LibreTiny versions, and an MCU link sensor. Update notes
with the raw capture results and tidy the README to-do list.
