suggested regression tests

describe('Email configuration validation', () => {
  it('should throw error when MAIL_HOST is not set', () => {
    delete process.env.MAIL_HOST;

  it('should throw descriptive error when SMTP_HOST is undefined', async () => {
    process.env.MAIL_HOST = undefined;
    await expect(sendEmail('test@example.com', 'Test', 'Body')).rejects.toThrow('Email configuration incomplete');
  });
});

missing coverage

services/notifications/email.tssendEmail should fail gracefully when SMTP_HOST is undefined
services/notifications/config.tsconfig should validate all required environment variables are set
services/notifications/email.tssendEmail should throw descriptive error when email config is incomplete
