fix(sql): handle record_id=0 correctly in CRUD utilities

Updated sql_select, sql_update, and sql_delete to use explicit 'is not None' checks for record_id. This prevents falsy ID values (like 0) from triggering generic table scans or failing to filter, which was causing the config bootstrap to accidentally load record ID 1 when ID 0 was requested.
