…che#62712) Problem Summary: Nereids always constructs a non-null alter job id list for `CANCEL ALTER TABLE`, using an empty list when the SQL omits explicit job ids. `SchemaChangeHandler` already treats an empty list as "cancel all unfinished jobs on the table", but `MaterializedViewHandler` only checked for `null`. As a result, `CANCEL ALTER TABLE ... ROLLUP FROM db.tbl` could incorrectly search by explicit job ids, find nothing, and throw `Table[...] is not under ROLLUP` even when the table still had unfinished rollup jobs. This change aligns `MaterializedViewHandler` with `SchemaChangeHandler` by treating an empty job-id list the same as an omitted list, and adds regression tests for both the handler path and the Nereids parser behavior.
