hikari ce59bf47f9 feat: add Prisma schema for pairing history ...

Add MongoDB schema with Prisma 6.8.2 for tracking:
- ServerEvent: events per server (coffee chats, study groups, etc.)
- UserPairingHistory: user pairing records per server
- PairingRecord: individual pairing entries with event context

This enables smart grouping that avoids recent pairings per-event.
