Portal backend: Facebook OAuth, social features, portal comments

- Facebook Login OAuth (meta-web auth service + routes)
- Account linking (merge Quest metaId + Facebook facebookId)
- User profile updates (bio, isPublic, displayName)
- Social endpoints: follow/unfollow, feed (trending/following/recent), likes
- Portal comments via WebSocket (subscribe_portal, send_portal_comment)
- Prisma migration: Follow, Like models, facebookId/bio/isPublic on User
- Provider OAuth source=web redirect support for portal callbacks
- Docker compose portal service, CORS multi-origin support
