createCalendarFeedLinkRecord failed with `overrideAccess:false` +
`user: campaignUser` because Payload stripped the required
`secretSlug`/`createdBy` fields (create access was admin-only) -> 400
behind the generic message; revokeCalendarFeedRecord silently no-opped
(revokedAt update access also admin-only).
- canCreateCalendarFeed now enforces advisor filterMunicipality scope
on data (canCreateSupporter precedent) + canSetCalendarFeedSecret /
canSetCalendarFeedRevocation permit staff to mint the secret on create
and mark a feed revoked; secret read stays `() => false` and update
admin-only.
- CalendarFeed stamps createdBy via stampCampaignCreatedBy; secret
create + revokedAt update use the new staff field accesses.
- Action refactored to `*Record` (payload, actor) cores + thin wrappers;
assertFilterMunicipalityInScope (tour precedent); console.error keeps
the real error on the server while the friendly message stays.
- 10 int tests for create/scope/revoke/leader/secret; fixture tracks
calendarFeed cleanup.
