UX-MOBILE-1: FilterPanel — einklappbare Filter auf Mobil (390px)

Neues FilterPanel-Muster (src/components/FilterPanel.tsx + filterPanel.css):
- Mobil (<768px): Suchfeld immer sichtbar; alle weiteren Filter hinter einem
  'Filter (N)'-Button eingeklappt (Badge = Anzahl aktiver Nicht-Default-Filter).
  Tippen öffnet/schließt den Drawer. 'Filter zurücksetzen' im Drawer.
- Desktop (>=768px): Toggle versteckt, Drawer als display:contents → alle Controls
  inline in der bestehenden .filters-Flexzeile, wie bisher.
Auf GerbilsPage, WuerfeListPage und AnfragenPage ausgerollt.
BeckenPage/KontaktePage nur ein Suchfeld → kein Panel nötig.

e2e: filter-panel.spec.ts (8 Tests, phone+desktop); bestand/tiere/anfragen-Specs
erhalten openFilterPanel-Aufruf vor Drawer-Controls; fixtures.ts +openFilterPanel().
Vitest 78 / e2e 102 grün.

Mobil-Pass (390px, Durchsicht): Hauptproblem behoben. Beobachtete Restpunkte
für god (nicht selbst gefixed):
- .genotype-table in Genetik/Probeverpaarung: Genotyp-Strings können eng werden
- Stammbaum (react-d3-tree SVG): kein explizites mobile Viewport-Handling
- BreedingResultView Genotyp-Detail-Tabelle: ggf. horizontal scrollbar-los
