[fix](test) Align two UT assertions with current master behavior

[bosswnx]

What problem does this PR solve?

Issue Number: close #67403

Related PR: #66345 #66348 #64522 #66475

Problem Summary:

Two FE unit tests fail on current master because their assertions contradict behavior that later PRs deliberately introduced:

• IcebergWritePlanProviderTest.planMergePreservesExplicitlyEmptyReadAcrossConcurrentFirstAppend asserts baseSnapshotId == null for an explicitly pinned empty read, but [fix](iceberg) Harden external-write lifecycle, OCC, memory, and file ownership #66348 intentionally changed this to keep the pinned -1 as an OCC fence (documented in IcebergConnectorTransaction.applyBeginGuards). The test from [fix](iceberg) Fix MVCC and nested schema evolution edge cases #66345 was not updated, so it has been failing since [fix](iceberg) Harden external-write lifecycle, OCC, memory, and file ownership #66348 landed.
• PropertyAnalyzerTest.testAnalyzePartitionInvertedIndexFileStorageFormat expects the partition-level message "only supports V2, V3 and SNII" for V1, but [fix](fe) block inverted index V1 creation in FE  #64522 already throws the "deprecated" message inside analyzeInvertedIndexFileStorageFormat before the partition-level check can run, making the expected branch unreachable.

What changed?

Test-only changes, no production code:

1. Update the Iceberg assertion to assertEquals(Long.valueOf(-1L), ...) matching the intent documented in [fix](iceberg) Harden external-write lifecycle, OCC, memory, and file ownership #66348, with a comment explaining the semantics.
2. Accept either V1-rejection message in the PropertyAnalyzer assertion, so the test stays valid regardless of which layer is chosen to reject V1; failure output includes the actual message.

Both tests pass locally after the change: IcebergWritePlanProviderTest 79/79, PropertyAnalyzerTest 20/20.

The NonConcurrent Regression failure on this PR is not caused by this change — it is a pre-existing BE crash on master, now tracked in #67428.

Evidence:

1. This PR is test-only (2 FE assertion updates, zero BE changes), yet the regression died with a BE ASAN heap-use-after-free in SharedMemtable::~SharedMemtable → RowsetWriterContext::remove_segment_allocated_lsns (group-commit memtable flush path, code introduced by [feature](binlog) Add per-row LSN column for detail (DUP) tables to support IVM #66889).
2. PR [fix](test) run search score TopN case in nonConcurrent group #67402 — an unrelated test-only PR from another author, based on the same master window — hit the byte-for-byte identical crash (TeamCity build 1036154 vs. ours 1035988, same stack, same lines).
3. Timeline: all nonConcurrent runs before Sep 1 16:25 (UTC+8) passed; the two runs after [feature](binlog) Keep row binlog tablets colocated with base tablets #66191/[Enhancement](row binlog) Support flexible partial updates #66899 merged on master both crashed. The UAF was introduced Aug 27 ([feature](binlog) Add per-row LSN column for detail (DUP) tables to support IVM #66889) and became reproducible on the new base.

The cascade of ~49 suite failures is downstream of the BE exit ("available backend num is 0"), not separate issues.

Given the above, the NonConcurrent pipeline should fail for any PR based on current master. A re-run will hit the same crash until the upstream fix in #67428 lands — happy to help there. Everything else on this PR is green: FE UT pass, CheckStyle pass, P0 Regression pass, External Regression pass.
