refactor(access): migrate to SDKConfig for authentication and provider management
- Replaced `config.Config` with `SDKConfig` in authentication and provider logic for consistency with SDK changes. - Updated provider registration, reconciliation, and build functions to align with the `SDKConfig` structure. - Refactored related imports and handlers to support the new configuration approach. - Improved clarity and reduced redundancy in API key synchronization and provider initialization.
