feat: integrate tooltip functionality across various components

- Added TooltipProvider and Tooltip components to enhance user experience with contextual information.
- Wrapped existing components such as TeamListView, TeamDetailView, and SendMessageDialog with tooltips for better interaction feedback.
- Implemented MessagesFilterPopover to allow filtering messages by sender and recipient, improving message management.
- Updated KanbanBoard and KanbanFilterPopover to include tooltips for view mode buttons, enhancing usability.

These changes aim to provide users with clearer guidance and improve overall interaction within the application.
