Replace the monolithic Sleep Tracking Stopped automation with an
input_boolean.awake flag plus input_datetime.woke_up timestamp.
Bedroom light and bathroom music trigger on the flag, music now runs
weekdays only, and the 45-minute music stop uses a template trigger
against the stored timestamp instead of a delay so it survives
Home Assistant restarts.
