fix(license): remove cascading commercial-use bit encoding, clarify Allow Selling label (#941)

- _resolve_commercial_bits() no longer has Sell-implies-Image
  cascading; each CommercialUse value sets only its own bit,
  matching CivitAI's modern array-format API.
- Keep filter tag label as 'Allow Selling' for brevity; add
  title/tooltip 'Allow selling generated images' on hover.
- Same tooltip treatment for 'No Credit Required'.
- Add i18n keys for both tooltips across all 10 locales.
