Implement Framework Import Modal with Enhanced Filtering and Styling

- Introduced a new modal for importing training framework sessions, featuring a backdrop and panel for improved user experience.
- Added comprehensive filtering options for focus areas, training types, and target groups, utilizing a structured filter state.
- Enhanced session duration handling with distinct duration collection and display, improving clarity in program selection.
- Updated utility functions to support new filtering capabilities and session duration management, ensuring a cohesive user interface.
