Decor Sounds 0.7.5 beta

- Optional server-time sound schedules for house backgrounds, room backgrounds,
  room effects and saved sound zones.
- Morning, afternoon, evening and night with editable 24-hour start times.
- Use the default sound, choose another recording, or silence each period.
- Automatic switches while indoors; the same looping recording keeps playing
  across a period boundary. Different recordings start from their beginning.
- Once-on-entry sounds may trigger again when the scheduled period changes.
- Schedules are included in saved builds, recovery drafts and duplicated zones.
- Scheduled house exports require Studio 0.7.7 and the cloud time-schedules patch.
- Existing setups remain unchanged until a schedule is enabled.
- Uses server time regardless of the minimap clock's local-time preference.
  Visitors evaluate their own client's server clock; cross-realm clocks may differ.
- No Armillary detection and no changes to game channel/volume preferences.
