Implement fixed-height month view rows with event overflow handling

- Change calendar grid to use equal row heights instead of min-height on cells
- Add "+n more" indicator for days with too many events to display
- Limit visible events to fit available space (default 3 events per day)
- Add window resize handler to recalculate event limits dynamically
- Remove gaps between calendar rows for cleaner appearance
