feat(person-mention): PersonHoverCard with skeleton/error/loaded states
The card has three render states:
- loading → 320×180 skeleton with three pulse-animated bars; respects
prefers-reduced-motion (animation disabled, opacity dimmed)
- error → generic load-error message in the body; the footer link
still navigates (click works regardless of fetch outcome)
- loaded → navy header with name, life-date range, and "geb. <alias>";
family-only relationship chips (PARENT_OF / SPOUSE_OF /
SIBLING_OF) — non-family types are filtered out;
notes excerpt capped at 120 chars with ellipsis;
footer with "Zur Person →" + hover hint
aria-live="polite" on the card root so screen readers announce loaded
content when the fetch resolves; the host's id is the cardId so the
parent anchor can use aria-describedby. The card is hidden via
@media (hover: none) on touch devices — tap navigates directly per
spec.
