fix(cashu): replace auto-popup with a tappable pending-quote banner

Bug: every entry to the wallet screen re-opened the Receive dialog if
any pending kind:7374 mint quote existed. So a user who got an invoice
and then navigated away — for any reason, even without dismissing —
would be greeted by the same invoice dialog the next time they opened
the wallet. Worse: even after they'd paid and the mint had issued
proofs, the brief window before the kind:7374 NIP-09 delete propagated
would cause the dialog to pop again.

Fix: drop the LaunchedEffect(pendingQuotes) auto-resume; replace with
a non-modal banner card just under the BalanceCard that shows
"N pending invoices · Tap to resume". The user opts in by tapping it.

The underlying CashuWalletState.pendingQuotes flow + the
viewModel.resumeMintQuote() VM method are unchanged — only the
trigger surface moves from "auto" to "user-initiated".

playDebug + fdroidDebug compile clean; 24/24 jvm tests still pass.
