Rewires briefwechsel-rows.visual.spec.ts against the shared fixture
(seedBilateralPair + cleanupBilateralPair), adds afterAll cleanup,
and folds the conv-person-bar visibility gate into openBilateral()
so both the structural test and the snapshot block fail loudly on
a hero-state regression — matching the a11y spec's safety net.

Extends the seeding pattern from the a11y spec: beforeAll creates two
persons + one document so the page renders the row layout. The
structural test now asserts the ConversationThumbnail tile AND the
DistributionBar are present — a regression that drops to the hero
or breaks the row wiring fails here instead of silently passing a
hero-state check.
Snapshot block stays gated on VISUAL=1 (baselines captured during
review against a seeded backend) so the structural coverage ships
immediately and the pixel-diff coverage ships once baselines land.

Fixes @saraholt blocker 2 from PR review

Adds a Playwright spec gated on VISUAL=1 with one snapshot per
(mobile/tablet/desktop × light/dark) = 6 baselines. Snapshots stay
skipped in CI until the baseline set is captured and committed —
running `playwright test --update-snapshots briefwechsel-rows`
against a seeded backend generates them.
Structural check runs unconditionally so the file is wired into CI
today rather than waiting for the baseline capture step.
