feat: include uploads folder in network sync (all three subfolders)

Daily sync and Sync Now both pull database + uploads in one operation.
PC1 streams uploads/ as a zip via GET /network-backup-files (archiver).
PC2 clears cloud-storage, patients, and patient-documents then extracts
the fresh copy before resolving. Timeout extended to 5 min for large files.
