feat: Add tag filtering and developer mode options in Identify and AutoMatch components

This commit introduces new features for tag filtering in the Identify and AutoMatch components. Users can now filter unidentified faces by tags, with options to match all or any specified tags. The UI has been updated to include tag selection and management, enhancing user experience. Additionally, developer mode options have been added to display tolerance and auto-accept threshold settings conditionally. The API has been updated to support these new parameters, ensuring seamless integration. Documentation has been updated to reflect these changes.
