feat(insights): Include all guests in CSV export

[devin-ai-integration]

Include guest information in CSV export from Insights page

This PR adds support for including all guests in the CSV export from the Insights page, not just the primary booker.

Changes

• Modified the CSV export logic to include all attendees for each booking
• Added an isBooker field to distinguish the primary booker
• Renamed fields from bookerName/bookerEmail to guestName/guestEmail for clarity
• Preserved all existing booking metadata while expanding guest information

Testing

Note: Local environment checks (lint, type-check, build) couldn't be run due to eslint plugin configuration issues. These will need to be verified in CI.

The changes are focused on a single file and maintain the existing data structure while expanding the guest information representation.
