Add PDF dropzone to audit list for streamlined report upload

Enable users to drag-and-drop PDF reports onto the audit list page, which automatically opens the create-audit dialog with the file attached. The dialog chains createAudit → uploadAuditReport mutations, with graceful handling for partial failures (audit created but upload failed).

Changes:
- AuditsPage: Add dropzone with visual overlay (dashed border + icon) when dragging PDFs
- CreateAuditDialog: Accept optional file prop, show file info, chain mutations on submit
- Extract audit ID from createAudit response to pass to uploadAuditReport
- Handle upload failure with warning toast, allowing manual upload from audit detail page
- Add react-dropzone dependency to console app
