FEAT-NAMEGEN UC-1: 'Name vorschlagen'-Panel auf GerbilFormPage

- api/names.ts: suggestNames() + buildSuggestPath() + NAMEGEN_USAGES (norn/japa/mythg/ger/arb)
- de.ts: namegen-Sektion (button, panelTitle, letter/usages/load/states)
- NameSuggestPanel.tsx: inline-Panel mit Buchstabe/Herkunftskultur-Multiselect, Vorschlagsliste; 503 NamesKeyMissing → freundlicher Hinweis
- GerbilFormPage: 'Name vorschlagen'-Button neben Namensfeld (htmlFor-Pattern), Panel schließt+befüllt bei Auswahl
- vitest: 11 Tests (buildSuggestPath URL-Logik + NAMEGEN_USAGES-Struktur)
- e2e: mock /names/suggest + namesConfigured-Flag; 4 Specs (Panel öffnen, Klick befüllt, Buchstabe-Filter, 503-Fallback)

Gate: vitest 104/104, e2e 156/156, tsc clean
