Replaced string-based entity identifiers in CRUD procedure and command classes with a strongly-typed EntityType enum. Updated all relevant handlers and records to use the new enum property, improving type safety and maintainability. Added necessary using directives and updated documentation comments to reflect these changes.
Renamed InsertActionProcedure, UpdateActionProcedure, and DeleteActionProcedure to their respective *ActionCommand counterparts to align with CQRS conventions. Updated all controller actions, handlers, tests, and related usages accordingly. No changes to business logic or method signatures.
