Fix orientation parameter handling and template URL endpoints

- Add orientation parameter support to create_group and edit_group functions
- Fix manage_group.html template URL endpoint from 'update_group_content_order' to 'update_group_content_order_route'
- Add orientation field and filtering to edit_group.html template with JavaScript functionality
- Update group_player_management.py to handle orientation validation in create and edit operations
- Fix docker-compose.yml to include build directive and correct volume paths
- Update entrypoint.sh to handle fresh deployments without migrations
- Ensure orientation consistency across group and player management

These changes resolve:
- Internal Server Error on manage_group page
- Missing orientation parameter in group creation/editing
- Template URL endpoint mismatches
- Docker deployment issues with fresh installations
