[I] test(amber): add unit test coverage for non-range partitioners [texera]

["aglinxinyuan (via GitHub)" <gi...@apache.org>]

URL: https://github.com/apache/texera/issues/4745

   ### Task Summary
   
   Four of the five partitioners under `amber/src/main/scala/org/apache/texera/amber/engine/architecture/sendsemantics/partitioners/` currently have no unit tests; only `RangeBasedShufflePartitioner` is covered (by `RangeBasedShuffleSpec`). Add `PartitionersSpec` covering the remaining four:
   
   - **OneToOnePartitioner** — `getBucketIndex` always emits `Iterator(0)`; `allReceivers` selects the channel whose `fromWorkerId` matches the actor id
   - **BroadcastPartitioner** — `getBucketIndex` yields every receiver index; `allReceivers` is deduplicated
   - **RoundRobinPartitioner** — `getBucketIndex` cycles bucket indices (verifying current contract that the first emitted index is 1, since the implementation increments before emitting); `allReceivers` preserves channel order while deduplicating
   - **HashBasedShufflePartitioner** — `getBucketIndex` is in-range, deterministic for the same hash-key, depends only on the configured hash-attribute subset, and falls back to the full tuple when no hash attributes are configured; `allReceivers` deduplicates
   
   ### Priority
   P3 – Low
   
   ### Task Type
   - [x] Testing / QA
