### What problem does this PR solve?
Issue Number: N/A
Related PR: N/A
Problem Summary:
`OptimizeGetAvailableMvsTest` could fail intermittently because
`TestWithFeService` reuses the same FE environment across test methods. If a
materialized view survived a failed assertion, a later case could see an extra
rewrite candidate. The partition-prune case also depended on asynchronous MTMV
refresh state before the materialized view became a rewrite candidate, so the
candidate map could be empty.
Root cause: In `OptimizeGetAvailableMvsTest`, test methods created
materialized views with fixed names and only dropped them at the end of the
happy path, so failed assertions could leave state behind for later test
methods. The partition-prune case also did not mock `MTMV.canBeCandidate()`,
which made the test depend on asynchronous MTMV refresh state.
Change Summary:
| File | Change Description |
|------|--------------------|
| `OptimizeGetAvailableMvsTest.java` | Drop test materialized views before
and after each test. |
| `OptimizeGetAvailableMvsTest.java` | Mock `MTMV.canBeCandidate()` in the
partition-prune case. |
