Complete calendar model refactor to use NaiveDateTime for local time handling

Browse Source 
- Refactor VEvent to use NaiveDateTime for all date/time fields (dtstart, dtend, created, etc.)
- Add separate timezone ID fields (_tzid) for proper RFC 5545 compliance
- Update all handlers and services to work with naive local times
- Fix external calendar event conversion to handle new model structure
- Remove UTC conversions from frontend - backend now handles timezone conversion
- Update series operations to work with local time throughout the system
- Maintain compatibility with existing CalDAV servers and RFC 5545 specification

This major refactor simplifies timezone handling by treating all event times as local
until the final CalDAV conversion step, eliminating multiple conversion points that
caused timing inconsistencies.
