refactor(api): alle handler auf api-helpers umstellen

13 +server.ts handler nutzen jetzt parsePositiveIntParam und
validateBody statt jeweils lokaler parseId/safeParse-Bloecke.

Konsequenzen:
- 9 lokale parseId/parsePositiveInt Definitionen geloescht
- 11 safeParse + manueller error()-Throws ersetzt
- domains/[id], domains, profiles: catch-Block reicht jetzt HttpError
  durch (isHttpError) — vorher wurde ein 404 vom updateDomain als 409
  re-emittiert
- recipes/[id]/image: kein function-clutter mehr neben den FormData-Pfaden
- Konsistente Error-Bodies: validateBody schickt {message, issues},
  parsePositiveIntParam {message: 'Missing X' / 'Invalid X'}
