fix(security): a dismissed status announcement no longer hides the security nudge (#307)

SecurityBanner asked pickBanner whether another strip would show without
the dismissed set, so a dismissed Kuma announcement (often pinned for
weeks) still counted and suppressed the verify / backup nudge on every
device that had dismissed it. The dismissed set is now a shared jotai
atom (still persisted to localStorage) used by both banners. Adds a
Playwright regression.

Fixes #307
