Convert test suite to TypeScript with async/await

[Copilot]

Modernized the test suite by converting all JavaScript test files to TypeScript and refactoring promise chains to async/await.

Description

Converted 21 test files and helpers from JavaScript to TypeScript. Replaced .then()/.catch() chains and callback-style tests with async/await patterns.

Key changes:

• All test/*.test.js → .test.ts with ES6 imports
• Helper functions in test/helpers/index.js → .ts with proper typing
• Callback-based tests (done) => {...} → async () => {...}
• Promise chains refactored to sequential await statements
• Fixed authentication test that was incorrectly expecting Content-Type header on 401 response

Infrastructure:

• Updated test command: NODE_OPTIONS="--import tsx" for TypeScript module loading
• Added test/tsconfig.json for test-specific compiler options
• Removed deprecated --require ./test/bootstrap.cjs approach

Example conversion:

// Before
it('should create task', (done) => {
  models.Task.create({ url: 'https://...' })
    .then(task => {
      expect(task.url).to.exist
      done()
    })
    .catch(done)
})

// After
it('should create task', async () => {
  const task = await models.Task.create({ url: 'https://...' })
  expect(task.url).to.exist
})

Bug Fixes:

• Removed incorrect Content-Type expectation from authentication test (test/user.test.ts). The /authenticated endpoint returns res.status(401).end() without a Content-Type header when authentication fails.

All tests maintain identical behavior. Type checking passes (npm run typecheck).

Thank you for your contribution!

In general, to fix insecure randomness in a security-sensitive context, replace uses of Math.random() with a cryptographically secure source such as Node’s crypto.randomBytes (or crypto.randomUUID) and derive the needed string/number from that. This ensures the generated values are not trivially predictable.

Here, the only insecure use is generateTestEmail, which uses Math.random() to generate the local-part suffix of a test email. The best minimal fix is to keep the overall behavior (unique-ish test emails) but change the implementation to use crypto.randomBytes to produce a random hex suffix instead of Math.random(). Concretely:

• Add an import of Node’s built-in crypto module at the top of test/helpers/index.ts.
• Change generateTestEmail from using `teste+${Math.random()}@gmail.com` to using a random string from crypto.randomBytes, e.g. `teste+${crypto.randomBytes(8).toString('hex')}@gmail.com`.
  No other logic (register, login, etc.) needs to change.

Fixed in commit eb9a255. The /authenticated endpoint returns res.status(401).end() without a Content-Type header when authentication fails, so I removed the incorrect .expect('Content-Type', /json/) assertion from the test.
