feat(memoro): add deployment infrastructure and migrate web services to new Hono server

- Dockerfile for audio-server (Bun + ffmpeg)
- docker-compose.macmini.yml entries for memoro-server (3015) and memoro-audio-server (3016)
- Dev commands: dev:memoro:server, dev:memoro:audio-server, dev:memoro:app, dev:memoro:full
- MEMORO_* env vars in .env.development
- web: add PUBLIC_MEMORO_SERVER_URL env var to env.ts and .env.example
- web: rewrite transcriptionService → POST /api/v1/memos (new server path)
- web: rewrite spaceService → /api/v1/spaces/* (aligned with actual Hono routes)
- server: fix callAudioServer param name audioPath (was filePath) in memos.ts
