The REST API archive action toggled an event's Archived
(retention-protection) flag with no authorization beyond the
controller's coarse "Events permission is not None" gate. Any
authenticated read-only user, including one restricted to a subset of
monitors, could flip the retention state of any event by enumerating
event ids, and the action was reachable over GET (CSRF-able).
Gate the write by direction: archiving (protects from purge) requires
view access via Event::canView(); un-archiving (re-exposes to purge)
requires edit access via Event::canEdit(). Both enforce the per-monitor
object-level ACL. Restrict the action to POST/PUT to block CSRF.
