Centralize stored procedure SQL generation in StoredProcedureBuilder,
allowing handlers to specify procedure name and return variable.
Removes manual SQL string building from DeleteObjectProcedure and
UpdateObjectProcedure handlers, reducing boilerplate and improving
maintainability.
Introduce StoredProcedureBuilder to centralize and simplify the construction of SQL stored procedure calls and parameter lists. Refactor DeleteObjectProcedureHandler, InsertObjectProcedureHandler, and UpdateObjectProcedureHandler to use this utility, replacing manual StringBuilder and parameter management. Improves code readability, reduces duplication, and standardizes parameter handling, including output parameters.
