优化rescourse读取方式

- Remove routes/mcp_resources.py (ui:// URI resolver endpoint)
- Frontend now directly accesses /robots/{bot_id}/skills/{server}/apps/{resource}.html
- Add Daytona fallback middleware to fetch files from sandbox on 404
- Add utils/daytona_file_fetcher.py for on-demand single file download
- Resolve merge conflict: keep voice, knowledge_base routes
