Say payouts go out within a week

[n13]

What

Payout timing copy in the mining rewards flow no longer promises Mondays.

• Confirm page: PAYOUT row reads "Within a week".
• Submitted page: "Payouts go out within a week. Nothing else to do."
• Already-claimed page: the row is now labelled "Payout" (same string as the confirm page) with "Within a week"; the separate "Next Payout" string is gone.

Widget tests updated; analyzer clean.

Reviewer model: GPT 5.6 Sol

Verdict (advisory): Approve

No blocking findings. The timing-copy change is consistent across the confirm, submitted, and already-claimed views; the removed Monday-specific localization symbols have no remaining references, and regenerating localizations reproduces the committed output.

Validation:

• git diff --check 11720aa7...f06bee3d — passed.
• flutter gen-l10n plus a generated-file diff check — passed.
• Changed-file dart format --output=none --set-exit-if-changed — passed (7 files, 0 changes).
• flutter test test/unit/mining_rewards_confirm_screen_test.dart test/unit/mining_rewards_wallet_screen_test.dart — passed (7 tests).
• Repository-wide analysis was stopped at the required 10-second cap; cold-wallet, miner, and SDK analysis completed cleanly before the cap, while mobile-app analysis had started but not completed. The exact-head GitHub Analyze check is successful.
