refactor(admin): split 9 more oversized lib/ files into focused modules

Files split by agents before rate limit:
  - dsr/api.ts (669 → barrel + helpers)
  - einwilligungen/context.tsx (669 → barrel + hooks/reducer)
  - export.ts (753 → barrel + domain exporters)
  - incidents/api.ts (845 → barrel + api-helpers)
  - tom-generator/context.tsx (720 → barrel + hooks/reducer)
  - vendor-compliance/context.tsx (1010 → 234 provider + hooks/reducer)
  - api-docs/endpoints.ts — partially split (3 domain files created)
  - academy/api.ts — partially split (helpers extracted)
  - whistleblower/api.ts — partially split (helpers extracted)

next build passes. api-client.ts (885) deferred to next session.
