feat(ui) : improve time-tracking UX, responsive tags, and task priority flag

- Add duplicate button in time entry drawer
- Make time entry blocks and list responsive (tags wrap, hide on narrow)
- Replace date filter input with calendar icon next to month title
- Fix scroll to current hour in calendar (use gridBodyEl)
- Show project color on ticket code in task cards and my-tasks
- Add red flag icon for high priority tasks in kanban and my-tasks
