fix(lint): resolve all ruff E402/F401/F841/I001 errors

- Move logger= after imports in planner/routes.py and setup_paddle.py
- Add # noqa: E402 to intentional post-setup imports (app.py, core.py,
  migrate.py, test_supervisor.py)
- Fix unused cursor variables (test_noindex.py) → _
- Move stray csv import to top of test_outreach.py
- Auto-sort import blocks (test_email_templates, test_noindex, test_outreach)
