Refactor: Move equipment price and mandatory status to Categorie relationship

- Created CategorieEquipement entity to act as a join table between Category and Equipment.
- Moved 'obligatoire' and 'prix' (formerly prixContribution) fields from Equipement to the new CategorieEquipement entity.
- Added Flyway migrations V14 and V15 to update the database schema and migrate existing data.
- Updated Categorie UI to use a select dropdown and price input for managing category-specific equipment configurations.
- Replaced 'equipement.obligatoire' and 'equipement.prixContribution' calls with their new category-level equivalents in logic and templates.
- Updated pricing calculation in Licence entity to source prices dynamically from the Categorie configuration.
- Updated Dotation generation logic to sync with category requirements automatically.
