format: no truncating u64 -> usize casts in gather_storage and ExtentBytes

check-32bit-casts.sh flagged two casts added by the previous commits; both values are bounded (checked by gather_storage's first walk, and built from a usize fetch length), so they go through addr::saturating_usize. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
