Fix Slack export to properly fetch activity data from Firebase

- Fetch activity data from Firebase instead of relying on in-memory function
- Check both activity_final_summary and activity_summary paths
- Added Promise.all to fetch notes and activity data together
- Added debug logging to track activity data retrieval
- Fixed both preview and actual send functions

The issue was that getActivitySummary() only works for candidates actively being monitored,
not for interviewers viewing ended sessions.
