feat: Dokumentengenerator — Vollständige Vorlage-Bibliothek + Frontend-Redesign

- Migration 020: Typ-Renames (data_processing_agreement→dpa, withdrawal_policy→widerruf) + 11 neue MIT-Templates (NDA DE/EN, SLA, AUP, Community Guidelines, Copyright Policy, Cloud Service Agreement, Data Usage Clause, Cookie Banner, AGB, Liability Clause)
- Backend: VALID_DOCUMENT_TYPES auf 16 Typen erweitert; /legal-templates/status nutzt jetzt dynamisches GROUP BY statt Hard-coded Felder
- searchTemplates.ts: loadAllTemplates() für Library-First UX
- page.tsx: Vollständig-Rewrite — Template-Bibliothek (immer sichtbar) mit Kategorie-Pills, Sprache-Toggle, optionaler Suche, Inline-Preview-Expand und Kachel-Grid; Generator-Section erscheint per Scroll wenn Vorlage gewählt
- Tests: 52/52 bestanden, TestLegalTemplateNewTypes (19 neue Tests) + aktualisierte Typ-Checks
