-Create a Contao 5.7 bundle (PHP 8.4)
-
-Vendor: MummertMedia
-Bundle: EventManagerBundle
-Composer name: mummert-media/eventmanager-bundle
-Type: contao-bundle
-
-This bundle is internal only.
-
-IMPORTANT:
-Only implement backend functionality.
-No frontend logic.
-No controllers.
-No services.
-No access logic.
-No event listeners.
-No future planning.
-Only backend entities and relations.
-
-====================================================
-GOAL
-====================================================
-
-Extend Contao backend with:
-
-1) New entity: tl_organization named Organisationen, just german translation
-2) New entity: tl_location named Veranstaltungsorte, just german translation
-3) Join table: tl_member_organization
-4) Join table: tl_calendar_events_organization
-5) Extend tl_calendar_events with:
-   - location_id (exactly one location) with dropdown in Backend (title ASC)
-   - organization assignment (multiple via join table)
-6) Extend tl_member so that:
-   - A member can belong to multiple organizations
-7) Extend tl_organization so that:
-   - Multiple members can be assigned to it
-
-Everything manageable via Contao backend only.
-
-====================================================
-DATABASE TABLES
-====================================================
-
-Use Contao DCA SQL definitions (DBAL 4 compatible).
-Do NOT use serialized fields.
-Do NOT use string length values like "255".
-Use integer values.

-DCA REQUIREMENTS
-====================================================
-
-1) tl_organization:
-   - Backend list view
-   - Editable fields
-   - Published toggle
-   - Alias field
-   - Type as select field with static options:
-     accommodation, shopping, culture

-     (store relation in tl_member_organization)
-
-2) tl_location:
-   - Backend list view
-   - Editable fields
-   - Published toggle
-   - Alias field
-
-3) tl_calendar_events:
-   - Add field location_id (select, mandatory)
-     foreignKey: tl_location.title
-   - Add multi-organization relation
-     (store relation in tl_calendar_events_organization)
-
-4) tl_member:
-   - Add multi-organization relation
-     (store relation in tl_member_organization)
-
-====================================================
-RELATION HANDLING
-====================================================
-
-Use proper many-to-many handling via join tables.
