feat: add TemplateGrid and TitleBar components with tests

- Implemented TemplateGrid component for displaying templates in a grid layout.
- Added calculateCardWidth helper function for dynamic card sizing.
- Created TitleBar component for displaying the title and points with interaction.
- Added unit tests for TemplateGrid and TitleBar components to ensure proper functionality.
- Introduced useStickyTabs and useTabNavigation hooks with tests for managing sticky tab behavior and navigation logic.
- Implemented useTemplateFilter hook for filtering templates based on video content.
- Added comprehensive tests for all new hooks and components to validate behavior and edge cases.
