Fix update_access message payloads for past meeting artifacts

Update the recording, transcript, and summary access_update playbooks
to only include the required fields for access control instead of
sending the entire data payload. Each now includes:

- Recording: id, meeting_and_occurrence_id, recording_access, participants
- Transcript: id, meeting_and_occurrence_id, transcript_access, participants
- Summary: id, meeting_and_occurrence_id, summary_access, participants

The participants field includes the V1PastMeetingParticipant structure
with lf_sso (username), host status, is_invited, and is_attended fields
for proper access control in OpenFGA.
