Pull request overview

This PR upgrades the backend dependency stack to TypeORM ^1.0.0 (and @nestjs/typeorm ^11.0.1) and updates backend services/repositories plus unit/integration tests (and one frontend view) to match new TypeORM APIs (e.g., findBy, object-based relations/select, EntityManager.dataSource). It also removes typeorm-seeding and related seed scripts/factories.

Changes:

• Bump TypeORM / NestJS TypeORM dependency versions and regenerate lockfile.
• Refactor TypeORM usage across services/repositories/tests (deprecated APIs → new APIs; relation/select syntax updates).
• Replace feature-flag exposure count mapping to use a computed exposureCount field and update UI/tests accordingly; remove typeorm-seeding scaffolding.

packages/backend/src/api/services/UserService.ts:53

• findBy() returns an array, so !isUserExists will always be false (even when no users are found) and the welcome email will never be sent. Check the array length instead.

    const isUserExists = await this.userRepository.findBy({ email: user.email });
    const response = await this.userRepository.upsertUser(user);
    if (!isUserExists && response) {
      this.sendWelcomeEmail(user.email, logger);
    }
