bug: payment pending on-chain copy differs from android #1000

Payment Pending shows different wording for an on-chain payment whose outcome is unknown on iOS and Android.

• iOS: "This transaction may have been sent. Its outcome is unknown. Do not start a separate payment."
• Android: "The transaction outcome is unresolved. Check its status before trying again. Other payments remain blocked. If available, use Retry original payment to authorize a fee for the same payment."

Figma has only the Lightning pending frame (Send (Edge cases) › Transaction pending Lightning), so neither wording has a design to follow.

Expected: one wording on both platforms, now that the screen can also show Cancel expired payment, translated in every shipped language.
