test(ui): Drop low-signal flaky SignUpStart unsafeMetadata test

[wobsoriano]

Description

Follow-up to #8500 and #8504.

The error fixed in #8500 only surfaced in Sentry and was never reported as a user-facing runtime issue. The fix was straightforward, since it only required adding the missing methods to the synthetic unsafeMetadata field in SignUpStart.

The unit test added for that path is flaky, even after #8504, so this PR removes it to avoid continued CI noise.

📝 Walkthrough

Walkthrough

This PR removes the unsafeMetadata test suite from SignUpStart.test.tsx and documents the change via a new changeset entry. The deleted test suite contained 53 lines verifying that signUp.create rejection with a ClerkAPIResponseError does not surface as an unhandled rejection when unsafeMetadata is provided. A .changeset/famous-bats-tan.md file was added to track this change.
