web-app-taiga: extract admin bootstrap into dedicated task; add robust upsert path

Add roles/web-app-taiga/tasks/01_administrator.yml to handle admin creation via 'createsuperuser' and, on failure, an upsert fallback using 'manage.py shell'. Ensures email, is_staff, is_superuser, is_active are set and password is updated when needed; emits CHANGED marker for idempotence.

Update roles/web-app-taiga/tasks/main.yml to include the new 01_administrator.yml task file, removing the inline admin logic for better separation of concerns.

Uses taiga-manage helper service and composes docker-compose.yml with docker-compose-inits.yml to inherit env/networks/volumes consistently.
