[Bug]: Wallet API - `wallet_revokeSession` doesn't clear pending transactions from that origin

### Describe the bug

Whenever we have a session created, if we have a pending transaction coming from that dapp origin, if we trigger the `wallet_revokeSession` it clears the wallet permissions but it does not clear pending transactions coming from that dapp

### Expected behavior

We should clear pending transactions from the given dapp, if session is revoked

Reproduce the flow with the MetaMask multichain test dapp, focusing on the wallet_revokeSession entry point and the pending transaction or signature request involved. Trace how revocation handles the dapp origin, then verify that its pending requests are cleared and can no longer proceed after the session is revoked.
