User Profiles: Manage and view user profiles.

Seeding the Database

To seed the database with fake data:

Install the faker library:
```
npm install @faker-js/faker
```

Create the seeder script (seeder.ts):

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { UserService } from './user/user.service';
import { CaseService } from './case/case.service';
import { CreateUserDto } from './user/create-user.dto';
import { CreateCaseDto } from './case/create-case.dto';
import { faker } from '@faker-js/faker';

async function bootstrap() {
  const app = await NestFactory.createApplicationContext(AppModule);
  const userService = app.get(UserService);
  const caseService = app.get(CaseService);

  // Seed users
  for (let i = 0; i < 10; i++) {
    const userDto: CreateUserDto = {
      name: faker.name.findName(),
      email: faker.internet.email(),
    };
    await userService.create(userDto);
  }

  const users = await userService.findAll();

  // Seed cases
  for (let i = 0; i < 20; i++) {
    const caseDto: CreateCaseDto = {
      title: faker.lorem.sentence(),
      description: faker.lorem.paragraph(),
      userId: users[Math.floor(Math.random() * users.length)].id,
    };
    await caseService.create(caseDto);
  }

  await app.close();
}

bootstrap();

Run the seeder script:
```
ts-node seeder.ts
```

This script will populate the database with 10 users and 20 cases using the faker library for generating random data.
