feat: Add workout program management

- Create database tables: workout_program, program_session, person_program_assignment.
- Add Flask blueprint `routes/programs.py` with routes for creating, listing, viewing, and deleting programs.
- Implement program creation form (`templates/program_create.html`):
    - Allows defining program name, description, and multiple sessions.
    - Each session includes a name and dynamically added exercise selections.
    - Uses `tail.select` for searchable exercise dropdowns.
    - JavaScript handles dynamic addition/removal of sessions and exercises.
- Implement backend logic for program creation:
    - Parses form data including multiple exercises per session.
    - Automatically finds or creates non-person-specific tags based on selected exercises for each session.
    - Saves program and session data, linking sessions to appropriate tags.
- Implement program list view (`templates/program_list.html`):
    - Displays existing programs.
    - Includes HTMX-enabled delete button for each program.
    - Links program names to the view page using HTMX for dynamic loading.
- Implement program detail view (`templates/program_view.html`):
    - Displays program name, description, and sessions.
    - Parses session tag filters to retrieve and display associated exercises.
- Update changelog with details of the new feature.
