feat(05-01): add preparePdf utility and fields/prepare API routes
- Installed @cantoo/pdf-lib for server-side PDF mutation - Created src/lib/pdf/prepare-document.ts with preparePdf function using atomic tmp->rename write pattern - form.flatten() called before drawing signature rectangles - Created GET/PUT /api/documents/[id]/fields routes for signature field storage - Created POST /api/documents/[id]/prepare route that calls preparePdf and transitions status to Sent - Fixed pre-existing null check error in scripts/debug-inspect2.ts (Rule 3: blocking build) - Build compiles successfully with 2 new API routes Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
