stefankoelleandopenhands d925ac1253 fix: display local timezone in API and web frontend instead of GMT ...

- Add TIMEZONE environment variable support (default: UTC)
- Convert naive UTC datetimes from database to local timezone in API responses
- Add timezone field to EventResponse and EventsListResponse Pydantic models
- Update web template to display timezone information
- Update PLAN.md to document timezone changes

This fixes the issue where events at 8:00 UTC would appear as 6:00 GMT by displaying times in the correct local timezone.
