✨ feat: make EuroOffice the default editor for new and existing installs

- isEuroofficeEnabled default: false → true
- isCollaboraEnabled default: true → false
- Add eurooffice to STARTUP_APPS so it installs automatically
- performMigrations(): one-time migration (guarded by
  eurooffice_default_migration_v1 flag) that forces existing installs
  to switch to EuroOffice on next mastercontainer start, overriding
  any prior explicit editor choice
- Call performMigrations() at index.php bootstrap
