### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary:
Doris routes external table column changes to connector metadata operations,
but Paimon did not implement those operations. External table property changes
were also only handled for `auto_analyze_policy`, so connector properties were
rejected during analysis or silently ignored.
This change implements Paimon column add/drop/rename and table rename
operations, routes external table property updates through `ExternalCatalog`,
and adds Paimon and Iceberg property update implementations with metadata cache
refresh.
### Release note
Support Paimon ALTER TABLE column and table rename operations, and
Paimon/Iceberg table property updates.
### Check List (For Author)
- Test
- [x] Regression test
- [x] Unit Test
- [ ] Manual test
- [ ] No need to test or manual test.
- Behavior changed:
- [ ] No.
- [x] Yes. Paimon supports ALTER TABLE column/table rename operations,
and Paimon/Iceberg external tables support property updates.
- Does this need documentation?
- [x] No.
- [ ] Yes.
Validation:
- `./run-fe-ut.sh --run
org.apache.doris.datasource.paimon.PaimonMetadataOpsTest,org.apache.doris.nereids.trees.plans.commands.info.ModifyTablePropertiesOpTest`
- `./build.sh --fe`
- `git diff --check`
The external-environment regression cases were added but not executed
locally because they require the Paimon and Iceberg test services.
