Fix skipped tests in Web CLI E2E test suite

[mattheworiordan]

Several tests in the Web CLI E2E test suite are currently skipped and need to be fixed:

1. domain-scoped-auth.test.ts: "should enforce API rate limiting consistently" - This test is skipped because rate limiting tests are unstable across different environments

2. reconnection-diagnostic.test.ts: "should handle rapid disconnection during handshake" - This test is skipped because it's flaky and the timing is too sensitive

These tests should be made more robust or moved to a separate test suite that can handle environment-specific variations.
