chore(test): remove legacy API test suite and related infrastructure

All tests from the legacy testSuite.mjs have been ported to the
self-contained integration test framework (*.test.mjs files). Each
new test file starts its own Harper instance, eliminating shared state
and the sequential-dependency model of the old suite.

Removes:
- integrationTests/apiTests/tests/ — 29 legacy test files + testSuite.mjs
- integrationTests/apiTests/utils/ — legacy test utilities (request.mjs,
  restart.mjs, schema.mjs, etc.) and security/ (OCSP/CRL tools for
  unported TLS tests)
- integrationTests/apiTests/config/envConfig.mjs
- integrationTests/apiTests/.env.example
- package.json: test:integration:api-tests script
- .github/workflows/integration-tests.yml: Integration API Tests jobs
  (Node.js matrix, Bun, Windows) — coverage now provided by the sharded
  Integration Tests jobs that run all *.test.mjs files

TLS tests (24_ocspVerification, 26_crlVerification) were not in
testSuite.mjs and required special mTLS/OpenSSL infrastructure;
they are deferred for separate migration.
