Subject: [PATCH] fix: handle unlimited traffic package selection and button
 text

- Fix falsy check: selectedTrafficPackage !== null instead of truthy
  (gb=0 for unlimited was evaluated as false, hiding the buy button)
- Show "Buy Unlimited" instead of "Buy 0 GB" for unlimited packages
- Add buyUnlimited translation key to all 4 locales
