feat(tournament): enhance match interaction and navigation

- Refactored match highlighting logic in TournamentGroupsTab to use a dedicated handleMatchClick method for better readability and functionality.
- Added a new event emission for navigating to match results in TournamentResultsTab, allowing users to seamlessly transition to the results view.
- Implemented styling for match states in TournamentResultsTab to visually distinguish between finished, live, and active matches, improving user experience.
