Refine calendar events: dot-only month timed, title-first week, no left border

- Month timed events: dot + title only, hover reveals translucent card
- Month all-day events: keep translucent fill
- Time right-aligned in month view (ml-auto)
- Week/day view: title on top, time underneath for better scanning
- Remove 2px left accent border from all events
- Set color:'transparent' on FC event data to prevent inline style conflicts
- Recurring repeat icon preserved in all views
