Per Playwright's own docs, routeFromHAR's notFound: 'fallback' sends
unmatched requests straight to the network -- it does not chain to
other, earlier-registered page.route() handlers via route.fallback()
the way I'd assumed. Since Playwright checks routes in
reverse-registration order, a handler registered in beforeEach (i.e.
before the test body's routeFromHAR call) is checked AFTER routeFromHAR,
whose catch-all pattern intercepts everything first and sends any miss
straight to the (nonexistent, in e2e) network -- my stub never got a
chance to run. Confirmed by a second CI failure with the same "Failed
to fetch" symptom even after the CORS-header fix.
Moved the mockFilterSelectionData(page) call to immediately after each
test's own routeFromHAR(...) call instead, so it's registered later and
checked first for that specific URL, with routeFromHAR's broader
pattern still handling everything else as before.

CI (https://github.com/paperless-ngx/paperless-ngx/actions/runs/29777331059)
failed every e2e test that reloads the document list, with the browser
throwing "TypeError: Failed to fetch". Root cause: the e2e harness only
starts the Angular dev server (no real backend), and relies entirely on
page.routeFromHAR(..., { notFound: 'fallback' }) to mock API responses,
falling through to the real network for anything not in a recorded HAR.
The new GET /api/documents/filter_selection_data/ request added by this
branch fires on every non-search reload() and isn't in any pre-recorded
HAR fixture, so it fell through to a real network call with nothing
listening on the other end.
Added a shared mockFilterSelectionData() helper that stubs an empty
response for that endpoint, registered via test.beforeEach() before each
affected test's own routeFromHAR() call in every spec file that
exercises document-list reload (document-list, dashboard,
global-permissions, settings, document-detail). Playwright resolves
routes in reverse-registration order, so the later-registered HAR route
checks first, calls route.fallback() on a miss, and defers back to this
earlier-registered stub instead of hitting the network.
Not verified locally (Playwright browser binaries aren't installed in
this environment and the user preferred not to install them); relying
on CI to confirm.
