fix: update tests for Express 5 compatibility and fix unit tests

- Fix unit tests
  - Update session validation to check for non-empty strings in commands
  - Fix session ID validation test data to use valid hex characters
  - Add mock implementations for UrlHighlighter and CastConverter
  - Fix HTML escaping in URL highlighter mock
  - Adjust timing precision test tolerance

- Fix integration test infrastructure
  - Replace deprecated done() callbacks with async/await in WebSocket tests
  - Add urlencoded middleware for Express 5 compatibility
  - Create test stream-out file for cast endpoint

- All unit tests (32) and critical tests (15) now pass
- Integration tests still need work to match actual tty-fwd behavior
