feat: implement user profile endpoints (GET & PATCH /users/me)

[Josue19-08]

🔖 Title

Implement user profile endpoints — GET and PATCH /users/me

---

📄 Description

Phase 2 of the roadmap (API-04 and API-05) is still pending. The `/auth/register` endpoint creates the user profile but there are no endpoints to retrieve or update it. This blocks the frontend from displaying or editing user data after login.

---

✅ Tasks to complete

• Create `UsersController` with `GET /users/me` endpoint (protected by `JwtAuthGuard`)
• Create `UsersService.getProfile(userId)` that queries the `users` table via `UsersRepository`
• Create `UpdateProfileDto` with optional fields: `displayName`, `username`, `profileImageUrl`
• Implement `PATCH /users/me` with multipart support for profile image upload (reuse pattern from `/auth/register`)
• Add validation: username uniqueness check on update
• Add unit tests for `UsersService` and `UsersController`
• Register module and update Swagger documentation

🗒️ Additional notes

• Follow the controller/service/DTO patterns documented in `docs/development/`
• `@CurrentUser()` decorator is available to extract authenticated user ID from JWT
• Profile image upload should follow the same Fastify multipart pattern used in `AuthController.register()`
• Username changes must check uniqueness against existing users (excluding current user)
