perf: disable tooltips in year calendar to fix lag

Fixed issue #5579 where the calendar selection dialog was very laggy.

The root cause was rendering ~365 individual Tooltip components when
opening the year calendar view (one per day with activity). This created
a huge number of DOM nodes and event listeners that caused significant
performance issues.

Changes:
- Added disableTooltips prop to MonthCalendar and CalendarCell components
- Disabled tooltips in YearCalendar's small month views
- Removed unnecessary TooltipProvider wrapper in YearCalendar
- Tooltips remain enabled in the default month calendar view

Performance improvements:
- Eliminates ~365 tooltip instances when dialog opens
- Reduces initial render time significantly
- Makes dialog interactions smooth and responsive

Users can still click on dates to drill down for details if needed.
