fix: SIWE e2e test timing out and breaking ci

[seaona]

Description

SIWE tests are timing out, making our ci broken, as they take very long to execute (there are several instances of waiting for event payload which take 20 seconds each, making reach the total limit of 80 seconds).
This updates the timeout limits for that spec to unblock ci (based on a similar fix @chloeYue did for another long test). The Confirmations team can investigate further if that's expected
