Connor Johnstone c599598390 Fix recurring event RRULE INTERVAL and COUNT parameter loss
This commit fixes a critical bug where INTERVAL and COUNT parameters
were being stripped from recurring events during backend processing.

Frontend was correctly generating complete RRULE strings like:
FREQ=WEEKLY;INTERVAL=2;BYDAY=TU,FR;COUNT=6

But backend was ignoring the complete RRULE and rebuilding from scratch,
resulting in simplified RRULEs like:
FREQ=WEEKLY;BYDAY=TU,FR (missing INTERVAL and COUNT)

Changes:
- Modified both events and series handlers to detect complete RRULE strings
- Added logic to use frontend RRULE directly when it starts with "FREQ="
- Maintained backwards compatibility with simple recurrence types
- Added comprehensive debug logging for RRULE generation
- Fixed weekly BYDAY occurrence counting to respect COUNT parameter
- Enhanced frontend RRULE generation with detailed logging

This ensures all RFC 5545 RRULE parameters are preserved from
frontend creation through CalDAV storage and retrieval.
