fix(fireflies): support V2 webhook payload format for meetingId mapping (#4221)

* fix(fireflies): support V2 webhook payload format for meetingId mapping

Fireflies V2 webhooks use snake_case field names (meeting_id, event,
client_reference_id) instead of camelCase (meetingId, eventType,
clientReferenceId). The formatInput handler now auto-detects V1 vs V2
payloads and maps fields correctly, fixing empty meetingId on V2 webhooks.

* fix(fireflies): guard against NaN timestamp, use stricter V2 detection

Address PR review feedback:
- Use Number.isFinite guard to prevent NaN timestamp propagation
- Use AND instead of OR for V2 detection since both meeting_id and
  event are required fields in every V2 payload
