### What changes were proposed in this pull request? The purpose of this change is to fix how `SHOW TABLE EXTENDED` formats table properties for v2 tables. ### Why are the changes needed? Fix a bug.Before this change, the code converted the redacted property entries into a single string too early, and the later `mkString` call operated on that string character by character. As a result, the `Table Properties` output could be formatted incorrectly. This update keeps the properties as a list of `key=value` entries until the final formatting step, so the command produces the expected bracketed, comma-separated property list. ### Does this PR introduce _any_ user-facing change? Yes. Execute show table extended： `show table extended in paimon.`dev_xxx` like 'test_show_table_extended';` Before this PR, the output result is: <img width="2448" height="604" alt="image" src="https://github.com/user-attachments/assets/c0034197-0848-4bd3-ba42-f08279489d31"; /> After this PR: <img width="1860" height="456" alt="image" src="https://github.com/user-attachments/assets/318e1778-36a5-4ccb-8725-4e48bfd7b4a4"; /> ### How was this patch tested? <!-- If tests were added, say they were added here.
