feat: add per-patient Local folder in Documents page backed by Cloud Storage

- Documents page shows a "Local Folder" card for each selected patient
  with an "Open in Cloud Storage" button that deep-links to their folder
- Cloud Storage page reads ?folderId URL param on mount and auto-opens
  the folder panel for seamless navigation from Documents
- Backend: GET /api/cloud-storage/patient-folder/:patientId endpoint
  that idempotently gets or creates a top-level CloudFolder per patient
- CloudFolder schema gains optional patientId field linked to Patient
- Disk directories for cloud storage folders now use the folder's name
  (e.g. "Xiaohui Wang/") instead of the opaque "folder-{id}/" path
