fix: remove duplicate CheckInstallStep mount and .env hot-reload (#41)

Two related sources of duplicate-handler accumulation in the bootstrap:

1. CheckInstallStep was mounted twice: once inside
   initializeControllers() and once unconditionally at the top level.
   The top-level mount has to stay because the install wizard must be
   reachable before MONGODB_URL is configured. Removed the inner mount
   so each startup registers it exactly once.

2. fs.watchFile on .env called initializeControllers() on every save,
   which re-ran .init(app) for ~60 route modules onto the same Express
   app instance (Express has no clean route un-registration) and spun
   another setInterval inside startInterval(). Removed the watcher;
   nodemon already restarts on file changes in dev, and production
   env changes require a process restart anyway.

After this change initializeControllers() is only invoked once, from
the MONGODB_URL startup gate.

Closes #41
