XWiki: add diagnostic and modern AuthService handling

- Added 05_set_authservice.yml to set XWikiPreferences.authenticationService
  to modern component hints (standard, oidc, ldap).
- Added _auth_diag.yml to introspect registered AuthService components and
  verify the active preference.
- Updated docker-compose.yml.j2 to use -Dxwiki.authentication.authservice
  instead of deprecated authclass syntax.
- Temporarily included AuthDiag task in 01_core.yml for runtime verification.
