fix(web): schedule saves, restart_required, health and current-status agree with the rig

Browse Source 
- POST /config/schedule and /config/dim-schedule accept a disabled per-day
  schedule with every day off (config.template.json's own shape); a day
  that is off keeps its posted times.
- POST /config/main sets restart_required from what the save changed:
  brightness, mode durations and plugin sections are applied live.
- /health is degraded (display_loop: stopped) when the service is inactive,
  the socket does not answer and there is no live heartbeat.
- /display/current-status no longer serves a stopped display's cached state
  when the socket and heartbeat both say it is gone (display_gone).
