Add bidirectional sync for binary files (PDF, images, etc.)

FileSyncBridge now handles binary fileRefs in addition to text docs:
- Downloads all binary files to temp dir on project connect
- Watches for binary file changes on disk and uploads via REST API
- Listens for Overleaf socket events (reciveNewFile, reciveNewDoc,
  removeEntity, reciveEntityRename) to sync remote changes to disk
- Tracks binary files by SHA1 hash to avoid redundant uploads
