Serial No: warehousing pricing + grading + hardware failure routing

- Grade options: High/Med/Low/Flagged (replaces A/B/C/D/F)
- assigned_price label → Recommended Price
- Client script: grade→price mapping (High→market_high, Med→market_median, Low→market_low)
- Flagged grade shows FLAGGED, no price, Dismantle status
- New fields: cpu_test (Pass/Fail), ram_test (Pass/Fail)
- CPU/RAM Fail → auto Flagged grade, Dismantle status, route to Dismantle warehouse
- Server-side validation prevents pricing on failed hardware
- pricing_status options updated: Needs Pricing/Priced/Flagged/Dismantle/Manual Override/Expired/Error
