"""
Jitsi JWT Token E2E Test Suite

Tests the /api/jitsi_token endpoint to verify:
  - Moderator tokens contain moderator=true in the JWT payload
  - Attendee tokens contain moderator=false in the JWT payload
  - Room claim is correctly scoped per request
  - Basic validation rejects malformed input

Run from project root:
