XWiki: two-phase bootstrap + extension install before enabling auth; add XOR validation

- Add 02_validation.yml to prevent OIDC+LDAP enabled simultaneously
- Introduce _flush_config.yml with switches (OIDC/LDAP/superadmin)
- Bootstrap with native+superadmin → create admin → install extensions (superadmin) → enable final auth
- Refactor REST vars (XWIKI_REST_BASE, XWIKI_REST_XWIKI, XWIKI_REST_EXTENSION_INSTALL)
- Update templates to use switch vars; gate OIDC block in properties
- Idempotent REST readiness waits
