✅ Fixed the duplicate method issue by removing the unused stub

  methods:
  - Removed validateDatabaseConfig() method that just threw an
  exception
  - Removed validateEntityConfig() method that just threw an exception
  - These methods were not called anywhere in the codebase
  - Fixed PSR-12 formatting issue (extra blank line before closing
  brace)

  The codebase is now:
  - Clean: No duplicate or unused methods
  - PSR-12 compliant: All coding standards passed
  - PHPStan level 9: No errors
  - All tests passing: 67 tests successful
  - Documented: Changes recorded in CHANGELOG.md

  These stub methods appeared to be placeholders that were never
  implemented or used, so removing them improves code clarity without
  affecting functionality.
