1-on-1 meetings filtered out

[robloxian2011]

Describe the bug
1-on-1 meetings that you organize are not displayed in the app. The filtering logic in filterMeetingsByDateRange requires humanParticipants.length > 1, but when you create a meeting, Google Calendar's API only
returns the invitee(s) in the attendees list—not you. This causes all 1-on-1 meetings you organize to be filtered out since they only have 1 participant in the API response.

To Reproduce

1. Create a 1-on-1 meeting in Google Calendar with one other person (e.g., a manager sync or direct report check-in)
2. Open MeetWise and connect your Google Calendar
3. Navigate to the Plan or Review tab
4. Notice the 1-on-1 meeting you created is missing from the list

Expected behavior
All meetings with at least one other participant should be displayed, including 1-on-1 meetings that you organize.
