Rewrite filename check + add price/currency check to image QC

Filename check:
- Rewritten to flexibly parse multiple H&M naming conventions
  (Display, DOOH, OOH, SOME STATIC, Social, POS, DS)
- Extracts country code, language code, dimensions, campaign number
- Scores based on how much metadata was extracted (not rigid pattern)
- Tested against real filenames: BG_bg, ES_es, NO-no formats

Price/currency check (new):
- Detects prices in images via LLM vision API
- Validates currency against global pricing reference (deterministic)
- Falls back to LLM validation for unknown countries
- Optional campaign pricing sheet validation when has_pricing=True
- Added to profile with weight 30

Profile weights rebalanced: filename 30, quality 40, price 30
