Move quiet hours from hub config to per-call service params

Quiet hours are now specified per send_telegram_notification call via
quiet_hours_start/quiet_hours_end params instead of being a hub-wide
integration option. This allows different automations to use different
quiet hours windows (or none at all).

- Remove quiet_hours_start/end from config options UI and const.py
- Add quiet_hours_start/end as optional HH:MM params on the service
- Remove ignore_quiet_hours param (omit quiet hours params to send immediately)
- Queue stores quiet_hours_end per item; each unique end time gets its
  own async_track_time_change timer for replay
- On startup, items whose quiet hours have passed are sent immediately
- Add async_remove_indices() to NotificationQueue for selective removal
- Timers are cleaned up when no more items need them
