Lifts the three-API-call seeding (create sender, create receiver,
create document) out of briefwechsel-a11y.spec.ts and into a
dedicated fixtures module. The spec now calls seedBilateralPair()
in beforeAll and cleanupBilateralPair() in afterAll so the test
DB doesn't accrue seeded rows across reruns.
Two caveats captured in the helper docstring: the backend has no
person-delete endpoint (only the document is purged), and the
timestamped last names make leftover persons collision-free.

The previous version navigated to /briefwechsel with no params, which
renders the hero state — axe-core scanned the hero, not the new
ThumbnailRow / ConversationThumbnail / DistributionBar. This commit
seeds two persons + one document via the API in beforeAll, then
drives the URL with ?senderId=X&receiverId=Y so each of the
36 test runs (3 viewports × 2 themes × 2 assertions) actually scans
the intended DOM. Also asserts that conv-person-bar is visible first,
so a regression that drops the page back to hero fails explicitly
rather than silently passing an empty sweep.

Adds a dedicated axe-core sweep for /briefwechsel so contrast or
semantic regressions on the new row layout fail independently of
the catch-all accessibility suite. Scoped to the main landmark so
shared chrome violations (if any) aren't double-reported.
