Refactor layout error assertion to use path normalization (#3203)

To prevent false negatives in tests due to path formatting differences:
* Updated expected error message to use `path.normalize(config.dbFile)` instead of `config.dbFile.split('./')[1]`, see docs: https://nodejs.org/api/path.html#pathnormalizepath
  * Ensures consistent behavior across platforms
  * Improves resilience when users provide paths with mixed or repeated slashes
