feat(wallet-ui): Ark send/receive tabs + Ark pay-with option on peer files

Browse Source 
Send modal gains an Ark tab (address/invoice/lightning-address via
wallet.ark-send), Receive gains an Ark address + QR tab, and the peer
file purchase confirm offers Ark alongside Cashu/Fedimint. Demo mock
exposes ark_sats in wallet.ecash-balance and deducts the chosen rail on
paid downloads.
