Backend for tracking print jobs from Elegoo/Orca Slicer: - PrintJob model: tracks pending/completed/cancelled jobs - API endpoints: create, list, complete, cancel jobs - needs_weighing flag on Spool: for cancelled print recalibration - Database migration for new table and column Workflow: 1. Slicer post-processing script creates pending job 2. User completes job → auto-deducts filament 3. User cancels job → flags spool for manual weigh-in Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
