fix: Resolve TypeError by correcting module dependency injection

This commit fixes a TypeError that occurred because the contactRoutes
module was being initialized before the contactController module.

The fix involves:
- Swapping the initialization order in server.js so the contactController is
  initialized before contactRoutes.
- Modifying contactRoutes.js to accept the initialized contactController
  as a dependency, rather than requiring it on its own.
