ISTWCMS-7275: Refactor block classes to rename and streamline logic.

Renamed block classes and labels for consistency: Keywords, References, and Authors blocks now reflect updated naming conventions. Removed redundant block form and submit methods to simplify code. Adjusted permissions to align with new keyword editing logic.
