fix(adminfront): fix auth redirection in tests and add custom field validation

- Skip auth redirect to `/login` when `_IS_TEST_MODE` is true to prevent test timeouts.
- Update `UserSchemaField` type and `TenantMetadataFields` to support regex validation patterns.
- Fix translation key for tenant profile metadata section title.
- Enhance OIDC mock data and mock endpoints in `users_schema.spec.ts`.
- Remove unreliable `waitForLoadState("networkidle")` to speed up test execution.
