Investigating the v6.2.0-sh Teams confirmation error

This is likely the same class of regression as #28555 (Google Meet videoCallUrl missing in v6.2) — both stem from the Calendar Sync refactor introduced in v6.2.

The booking confirmation flow for Microsoft Teams goes through the credential resolution and event creation pipeline in packages/features/bookings/lib/. In v6.2, RegularBookingService.ts restructured how integration results are collected, which can cause the MS Teams credential or event reference to be looked up from the wrong result entry, or not found at all — throwing an error during confirmation.

Questions to narrow this down:

1. Does the error appear in the server logs? If so, can you share the stack trace or error message from the logs (not just the UI error)?
2. Is the MS Teams app connected under the same user account that owns the booking, or via an org-level credential?
3. Does confirming a booking that uses a different video provider (e.g. Zoom, Google Meet) succeed on the same instance?

If it's the same root cause as #28555, the fix in RegularBookingService.ts (dynamically resolving the correct result by provider type instead of hardcoding results[0]) should address this too.

Hi! I've opened a draft PR addressing this issue:
#28810

The fix replaces the hardcoded results[0] lookup with a dynamic
.find() scoped to office365_video, consistent with the approach
used in PR #28689 for the Google Meet regression (#28555).

Happy to make any changes based on your feedback!
