Implemented Authentication & User-Specific Resumes

Changes

• ✅ Authentication: Integrated Laravel Breeze for login, registration, and logout.
• ✅ User-Specific Resumes: Implemented Eloquent relationships to associate each resume with a user.
• ✅ Access Control via Middleware:
  • EnsureUserHasNoResume: Blocks users from creating multiple resumes; redirects to index with an error message.
  • AuthorizeResourceAccess: Prevents users from accessing resumes they don’t own (unless admin).
  • AdminMiddleware: Grants admin access to view all resumes; unauthorized users get a 403 error.
• ✅ UI Restriction: The "Add New" button is hidden once a user creates a resume.
• ✅ Direct URL Restriction: Trying to access /create after submitting a resume redirects with an error.
• ✅ Unauthorized Access Handling: Users cannot access other people's resumes (403 error).

Bonus Features

• 🔹 Admin Role: Allows admins to view and manage all resumes.
• 🔹 Basic Tests: Added authentication and access control tests.
