Subject: [PATCH] feat(sdk-core): forward isWalletConnectTx through TSS
 prebuild path

Surface the client-supplied WalletConnect marker through
PrebuildTransactionWithIntentOptions and PopulatedIntent so that
wallet-platform can classify txChannel.connector = 'walletconnect'
even on wallets that lack the enableWalletConnect flag.

Previously both the case 'transfer' field list in
prebuildTransactionTss and the EVM payment return in populateIntent
silently dropped isWalletConnectTx before it reached body.intent.

Ticket: DEFI-1013
