Align PersonCard's "unbestätigt" badge with the authoritative provisional
flag so the badge, the "Zu prüfen (N)" count and the /persons/review triage
list can never disagree. Empty/"?" name handling is now a separate
crash-safety concern: it still routes to the neutral placeholder glyph
(never a "?" initial) but no longer implies a badge on its own.
