Zed + Opus 4.6; prompts:
* Where was the bug fixed in b3618c351c6b2b153b7025fcd068407915f3f105
introduced?
* Add tests that fail before the fix commit and pass after.
* I stood up the database, so the tests should be runnable now. Test
both the current code (should pass) and prior to
b3618c351c6b2b153b7025fcd068407915f3f105 (will require renaming function
calls in the test; should fail).
Had to add the last prompt because MySQL wasn't running at the time of
the second prompt.

## Summary by CodeRabbit
* **Tests**
* Added regression tests ensuring replica setups read passwords from
disk and preserve TLS settings so connection behavior is validated.
* Added a helper to create and clean up temporary test databases used by
the new tests.
