### What problem does this PR solve?
Issue Number: N/A
Related PR: #69452
Problem Summary:
Backport #69452 to branch-4.1. Iceberg's JDBC catalog implements
`ViewCatalog` even when its V0 metadata schema does not support views.
Unsupported view probes must not prevent ordinary table listing or reads.
Adapt the fix to the release branch's legacy `IcebergMetadataOps`
implementation. Return no views only for unsupported JDBC view probes,
preserving V1 view support, REST view routing, explicit view-operation
failures, and real SQL/authorization errors.
Port the six unit-test scenarios to the legacy metadata API and retain the
original PostgreSQL V0 SELECT-only regression setup and read/time-travel checks.
### Release note
Fix table discovery and access through Iceberg JDBC catalogs using the V0
metadata schema without view support.
### Check List (For Author)
- Test
- [x] Unit Test: 19 tests passed (six new JDBC probe tests and the
existing metadata-operation tests), zero failures/errors/skips. FE Checkstyle
passed. Before the fix, both V0 tests reproduced the actual SDK
unsupported-view exception.
- [ ] Regression test: V0 scenarios ported unchanged from #69452;
release-branch end-to-end execution is left to CI.
- Behavior changed:
- [x] Yes. Unsupported JDBC view probes no longer block ordinary table
operations.
- Does this need documentation?
- [x] No.
### Check List (For Reviewer who merge this PR)
- [ ] Confirm the release note
- [ ] Confirm test cases
- [ ] Confirm document
- [ ] Add branch pick label
