Connor Johnstone d0aa6fda08 Fix critical weekly recurring event BYDAY rendering bug
This commit resolves a significant bug where weekly recurring events with multiple selected days (BYDAY parameter) were only displaying the first 2 chronologically selected days instead of all selected days.

## Root Cause:
The `next_weekday_occurrence` function was designed for single-occurrence processing, causing it to:
- Find the first matching weekday in the current week
- Return immediately, skipping subsequent selected days
- Repeat this pattern across weeks, showing only the same first day repeatedly

## Solution:
- **New Function**: `generate_weekly_byday_occurrences()` handles multiple days per week
- **Week-by-Week Processing**: Generates events for ALL selected weekdays in each interval
- **Comprehensive Logic**: Properly handles INTERVAL, COUNT, UNTIL, and EXDATE constraints
- **Performance Optimized**: More efficient than single-occurrence iteration

## Technical Details:
- Replaced linear occurrence processing with specialized weekly BYDAY handler
- Added comprehensive debug logging for troubleshooting
- Maintains full RFC 5545 RRULE compliance
- Preserves existing functionality for non-BYDAY weekly events

## Expected Result:
Users creating weekly recurring events with multiple days (e.g., Mon/Wed/Fri/Sat) will now see events appear on ALL selected days in each week interval, not just the first two.

Example: "Every week on Mon, Wed, Fri, Sat" now correctly generates 4 events per week instead of just Monday events.
