feat(ui): donate tab in Help overlay

Help button now shows a two-tab overlay: - Info: existing about/version content - Donate: donate flow to the dev address (plm1qdq3…) with free amount input, prepare preview, and confirm-and-broadcast button New MainWindowViewModel.Donate.cs partial: DonateAmount / DonatePreview / HasPendingDonate observable properties, PrepareDonateCommand (builds the tx with hardcoded dev address via the existing TransactionFactory), ConfirmDonateCommand (broadcasts and syncs). Donate state is reset on overlay close. Six-language Loc keys added (help.tab.info/donate, donate.desc/dev.address/amount/prepare/confirm). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
