fix(nwc): scope Send/Receive/Transactions to the wallet shown in the detail screen

The wallet detail screen's Send, Receive and Transactions buttons navigated to
parameterless routes. Each destination created a fresh WalletViewModel with no
selection, so the action ran against `_defaultWalletId` (the account default)
instead of the wallet being viewed. Paying, invoicing, and listing
transactions could therefore go to the wrong wallet.

Parameterize WalletSend/WalletReceive/WalletTransactions with `walletId`,
plumb it through AppNavigation, pass it from WalletDetailScreen, and have
each screen call `selectWallet(walletId)` before operating.
