Fix mypy type-checking errors

- Remove unused type ignore comments from multiple files
- Fix TypedDict type mismatch in browser_env/actions.py by ensuring arguments are converted to strings
- Install missing type stubs (types-requests, types-tqdm)

All core packages (browser_env, agent, evaluation_harness, llms, tests) now pass mypy checks.
