Add 3 homepage scan e2e tests covering all roaster/roast match
permutations (new+new, existing+new, existing+existing). Fix
StaleElementReference in checkin test by using JS clicks for
Datastar-managed DOM elements.
Cover the check-in flow where neither the cafe nor the roast exist
beforehand. The test searches for a cafe via location search (mocked
Foursquare), scans a coffee bag via text prompt (mocked OpenRouter),
and submits the check-in. Adds spawn_app_with_all_mocks helper.
Cover tab switching, search, pagination, and sorting on the data list
page. Verify detail page rendering for roasters, roasts, bags, gear,
and cafes. Test the close-bag flow from the detail page. Check that
home, stats, and timeline pages load correctly with data.
Roaster creation (basic + all fields), full brew chain through browser,
entity deletion with confirm dialog, AI extraction via text prompt with
mocked OpenRouter, and check-in wizard with saved cafe + existing roast.
BrowserSession wraps headless Chrome via thirtyfour. Auth helper injects
session cookies to bypass WebAuthn. Wait helpers handle Datastar's async
DOM updates (visibility, text, URL). Form helpers find visible elements
to avoid hidden duplicates on tabbed pages. Chromedriver is auto-spawned
on first use via a dedicated parked thread with PR_SET_PDEATHSIG so the
kernel kills it when the test binary exits.
