fix: adapt tests for CI environment

- alphabetical_order_test: avoid calling codecept.run() which hangs
  in CI due to container.started() and event listener setup; test
  loadTests() directly instead
- worker_test: revert custom config assertions to original 4.x
  relaxed values (exact counts are filesystem-dependent)
- worker_test: simplify distribution test to only verify suite
  distribution without assuming glob order
