Add Get endpoint and refactor ReadRecActionQuery

Added a new Get endpoint to RecActionController to fetch data
based on profileId using ReadRecActionQuery. Updated
ReadRecActionQuery to support long ProfileId, added a
parameterless constructor, and refactored its structure.
Adjusted ReadRecActionQueryHandler to align with these changes.
