fix(price): remove baseprice detection, use directional price match

baseprice > price was wrongly treated as "quantity discount" — it's just
GoMag's promotional price. Now: price_gomag <= pret_roa is always OK,
only flag when GoMag charges MORE than ROA. Reset cached price_match
at startup for re-evaluation. Fix dashboard dot color for mismatches.
