* fix(s3): re-check routed self-copy eligibility on the locked read

routeInPlace was decided on the pre-lock entry, but the PATCH body
re-reads the entry. A concurrent write changing file mode or MIME in
between left the routed PATCH installing new ACL keys while Attributes
kept the stale mode. Evaluate eligibility against the re-read entry and
retry the self-copy under the distributed lock when it no longer
qualifies.

* fix(s3): guard metadata self-copies against concurrent writes

* ci: raise s3api unit-test timeout to 9m

The suite crossed the 5m binary timeout on the hosted runner (local run
is ~4.3m and still growing). The job-level limit is already 10m.

* ci: allow setup time before the S3 API test suite
