Replace combined filament dropdown with separate material + color dropdowns

- app/constants.py: MATERIALS and COLORS standard value lists
- Migration 0008: job_material + job_color columns on print_jobs
- Job creation (both /jobs and /brackets/{id}/jobs) stores these independently
  of the filament inventory
- All job tables updated to display job_material · job_color
