fix: Use flexible date range for planning slots to capture cross-month slots

- Changed date range filter from strict to flexible boundaries
- Now captures slots that start before or end after the target month
- This should fix issue where Areli Romo shows only 25 hours instead of 99:33
- Uses relativedelta to extend range by 1 day on each side
- Ensures all slots that overlap with the month are included
