Lab #3387: Docs: grant and revoke changes reach every serve instance within one poll interval (S3/GCS and v2 filesystem)

What changed

swamp-club#3371 (PR #3070) made swamp serve on a v2 filesystem datastore reload its policy snapshot when another process changes grants or groups, within one --datastore-poll-interval (default 30 s). That was already true on S3/GCS datastores. The manual describes neither.

The manual today says changes are staged until reload:

content/manual/explanation/swamp-serve.md, "Policy snapshot and reload": "The snapshot is rebuilt on swamp access reload or automatically on every change when --grant-reload auto is active."
content/manual/how-to/swamp-serve/manage-access-grants.md, "Reload the policy snapshot": "Grants are staged until you reload."

Behaviour to document (both reload modes)

Changes made through this instance (--server to it) stay staged until swamp access reload in manual mode, and apply at once in auto mode. Unchanged.
Changes made by another process apply on this instance within one poll interval, in either mode. Another process means a peer serve instance on the same datastore, a local swamp access grant/revoke/group without --server, or a remote worker. Revokes do not need access reload on every peer.
- S3/GCS: the access data poller pulls data/swamp/grant and data/swamp/group and reloads on a change.
- v2 filesystem: serve checks the shared grant and group data for changes from other processes.
- v3 datastores allow one serve at a time, so this does not apply.
Network filesystems: with attribute caching (for example NFS actimeo), a change can show up later than the poll interval.

Suggested pages

Add a short "Multiple instances" paragraph to the "Policy snapshot and reload" section of the explanation page.
Add a note under "Reload the policy snapshot" in manage-access-grants.md that access reload applies the local instance's staged changes. Peers pick up changes within one poll interval.
Optionally link both from how-to/swamp-serve/run-multi-instance-deployment.md.
