fix: currency suggestion uses region detection, seed adds market prices

- Currency auto-suggestion now uses locale region subtag (en-US → US → USD,
  en-DE → DE → EUR) instead of language prefix. Fixes wrong suggestion for
  users with English browser locale in European countries.
- Added dismiss button (X) to suggestion banner
- Dev seed script now clears existing dev data before re-seeding (safe to
  run repeatedly without manual DB cleanup)
- Added DEV_MARKET_PRICES with multi-market UVP data for 10 global items
  (EU/US/UK prices) and community prices for 5 owned items
