Description

Problem:
The SIWE and other signature tests have been experiencing flakiness, primarily due to unnecessary timeouts at the end of each test. These timeouts occur because the test setup waits for all mock requests to finish, even if some of those requests are not relevant to the specific test. This results in the tests waiting for API endpoints that were never called, causing unnecessary delays and timeouts.

Solution:
To resolve this, the fix involves splitting the mocked endpoints into two separate functions. Most signature-related tests only need to check for "Signature Approved" or "Signature Rejected" events, so these endpoints are isolated into a dedicated function. This change ensures that only the necessary mock endpoints are passed to each test, reducing the likelihood of waiting for unused endpoints and improving overall test reliability.
