Ajout d'une colonne jsonb options sur csv_bookings (+ migration), stockee a la

- Replace localStorage.getItem('access_token') with getAuthToken() which
also checks sessionStorage — fixes Unauthorized error for users logged

onDragOver/onDragLeave/onDrop handlers on the dropzone container,
isDragging state with visual feedback (blue border + text change),
click-to-browse still works via hidden input ref
