Subject: [PATCH] fix(backend-test-utils): increase MySQL connect and pool
 timeouts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mysql2 driver defaults to a 10-second connect timeout, which is
too short when many test suites share a single MySQL container under
CI load. Increase the connect timeout to 30 seconds and add pool
acquire/create timeouts of 30 seconds to reduce flaky ETIMEDOUT
failures.
