   Thanks @manuzhang  for this backport and @huaxingao for merging it.
   
   I verified it against the repro in #16157: on stock 1.11.0, a merge-on-read UPDATE/DELETE on a natively-encrypted (format-v3) table fails on the next read with IllegalStateException: Null key metadata buffer. Building iceberg-spark-runtime-4.0 + iceberg-aws-bundle from 1.11.x with this change resolves it - the MOR update/delete round-trips, and the deletion-vector Puffin files are now written with encryption key metadata.
   
   Since this is on the 1.11.x branch now: is a 1.11.1 patch release on the near-term radar? And separately, any expected timeframe for 1.12.0 (which carries #15911)?
   
   Issue #16157 appears to be the same bug (its stack trace matches exactly) but isn't linked here, so it's probably worth linking and closing it once a release ships.
