[tiering] Fix Paimon IOManager leak in MergeTreeWriter causing /tmp disk exhaustion

The IOManager created in MergeTreeWriter.createTableWrite() was passed
inline to withIOManager() without keeping a reference. Since Paimon's
TableWriteImpl does not own the IOManager lifecycle, it was never closed,
leaving paimon-io-<UUID> directories in /tmp after each tiering task.

This fix stores the IOManager as a field and explicitly closes it in
close() via a finally block, ensuring temp directories are cleaned up.
