fix: Tufts SCO + UnitedDH pre-auth file upload, tooth fill, PDF and pre-auth number

- Frontend: upload attachments to disk before sending pre-auth payload (same pattern as claims)
- cloud-storage: finalizeFileUpload returns diskPath so Python workers get real file paths
- upload-to-cloud route: return diskPath instead of API URL
- TuftsSCO preAuth worker: skip 'Add a file' button click; send_keys directly to hidden react-aria-Input
- TuftsSCO preAuth worker: JS focus() on tooth field to bypass warning-banner overlay
- TuftsSCO preAuth worker: 1.5s wait after procedure code for layout shift to settle
- TuftsSCO preAuth worker: step8 waits for 'thank' in page_source then extracts via 'submitted pre-authorization' regex
- helpers_tuftssco_preauth: convert pdf_path → pdf_url (http://localhost:5002/downloads/...)
- tuftsSCOPreAuthProcessor: use pdf_url (not pdf_path), save preAuthNumber to preAuthNumber field
- unitedDHPreAuthProcessor: save preAuthNumber to preAuthNumber field (not claimNumber)
