XWiki: LDAP/OIDC admin mapping, config mounts, and REST installs

- LDAP: move settings to xwiki.cfg; enable trylocal (1/0), group_mapping to XWiki.XWikiAdminGroup,
  and mode_group_sync=always.
- OIDC: add groups claim request (oidc.userinfoclaims), map provider group to XWiki.XWikiAdminGroup,
  and use space-separated scopes.
- Compose: mount xwiki.cfg and xwiki.properties into /usr/local/xwiki.
- Extensions: wait for REST readiness; pre-check OIDC/LDAP extensions (URL-encoded IDs);
  install via REST job only if missing.
- Vars: strict mappings to LDAP.* and OIDC.* (no defaults), add XWIKI_ADMIN_GROUP and derived DNs.
- Config: expose ldap.local_enabled; tidy meta tags; README grammar update.
