The browser job of #1041 hung twice in a row in tests/e2e/test_column_filters.py (5-minute timeout), with two live-server request threads stuck inside SQLite: one serving the job list, the other serving /offline/.

Only the service worker requests /offline/. tests/e2e/conftest.py blocks service workers through browser_context_args (#895), but that reaches only the page and context fixtures. 79 contexts in 37 files are opened with browser.new_context() (phone viewport, scripts off), and in those the worker still installs and fetches the offline page in the background. That request lands while the next request is in flight, and both share the live server's single in-memory SQLite connection, which Django warns against.

Fix: every context the suite opens blocks service workers unless the test passes service_workers="allow".
