OnSched 3.8.2 - resource timezone updates

API

• Resource timezone updates: PUT /v3/resource/{id} with { "timezone": "<IANA>" } now reliably repoints weekly schedule rows to the new timezone, including when an equivalent (dayOfWeek, startTime, endTime, iana) row already exists in the shared WeeklyUnavailability table.
• Response consistency: Successful timezone updates return WeeklyUnavailabilities with the new iana values instead of stale pre-update rows.
• The same fix applies to Location and company-scoped Service timezone sync paths that share this WeeklyUnavailability repoint logic.
