### What problem does this PR solve? Backport the AlterMTMVTest deflake from #56997 to branch-4.1. On branch-4.1, `testAlterMTMV` creates an MTMV with `BUILD IMMEDIATE` and then asserts the rename result through `getCandidateMTMVs()`. Candidate collection depends on refresh/candidate-ready state, so the test can observe a legal intermediate state before the async refresh path has finished. The test intent here is to verify that the MTMV relation mapping is updated after renaming `mv_a` to `mv_b`, and that an MTMV cannot be used as the replacement target for `ALTER TABLE ... REPLACE WITH TABLE`. ### What is changed? Use the same shape as the master-side fix in #56997: - create the MTMV with `BUILD DEFERRED` - assert the relation mapping through `getMtmvsByBaseTable(...)` - keep the original rename and replace-table assertions ### Check List - [x] `git diff --check` - [x] `./run-fe-ut.sh --run org.apache.doris.mtmv.AlterMTMVTest` reached `Tests run: 1, Failures: 0, Errors: 0`; the remaining Maven reactor was interrupted after the target test per local handoff decision Related: DORIS-26807 -- This is an automated message from the Apache Git Service.
