feat(routes-f): viewer live queue for hosting endpoint

[davedumto]

Overview

Implement app/api/routes-f/live/queue/route.ts for a viewer participation queue (e.g., join queue to play with streamer).

Scope

• GET /api/routes-f/live/queue?stream_id= — returns current queue state (position, total, open/closed)
• POST /api/routes-f/live/queue/join — viewer joins queue (stream_id)
• DELETE /api/routes-f/live/queue/leave — viewer leaves queue (stream_id)
• POST /api/routes-f/live/queue/next — creator advances queue to next participant

Acceptance Criteria

• Queue is FIFO; position returned to viewer
• Creator can open/close queue via PATCH /live/queue {open: boolean}
• Max 100 viewers in queue per stream
• Route lives exclusively in app/api/routes-f/live/queue/
