Replace auth()->user() with Dependency Injection

[Nima8FT]

Summary

Replaced all usages of auth()->user() with proper dependency injection to improve testability and architecture.

Changes

• Updated controllers to inject Authenticatable or User instead of using global auth() helper.
• Ensured all routes using these controllers are protected by auth middleware.

Fix #344
