Track exact PriceCharting slab grades

[poketonova]

Summary

• resolve exact graded PriceCharting products through the existing strict identity matcher, then load the complete public grade guide through a constrained same-origin endpoint
• track Grade 1–9.5 exactly and keep PSA/BGS/CGC/SGC/ACE/TAG 10, BGS Black, and CGC Pristine as distinct price tiers
• stop substituting PSA 10 or Grade 9 for other companies/grades, and preserve missing graded prices as unknown instead of manufacturing a tracked $0
• add focused JavaScript and Python regression coverage for exact tier mapping and full-guide parsing

Live verification

Validated against PriceCharting product 11747998 (Ahri Signature): Grade 9.5, PSA 10, BGS 10, CGC 10, SGC 10, ACE 10, BGS Black, and CGC Pristine all parsed as distinct values; missing Grade 9 remained unavailable.

Verification

• npm run eval:harness
• npm run eval:danger
• Node 22 production build
• git diff --check
• npm run smoke:browser attempted; skipped locally because Chrome is unavailable (CI installs Chromium)
