Regenerate example code + fix broken paths from repo restructure

- Fix testapp/apps.py: import djarea_clients (file was never renamed)
- Fix fetch.mjs: command is export_djarea_schema not export_mizan_schema
- Fix harness package.json: dependency path to mizan-react after restructure
- Add package.json for generator (openapi-typescript dependency)
- Regenerate all example code with new protocol format:
  - generated.provider.tsx uses raw context responses + SSR hydration
  - generated.server.ts uses GET /ctx/global/ with response.ok check
  - generated.forms.ts, channels.ts, channels.hooks.tsx refreshed
- Remove stale generated.django.tsx and generated.django.server.ts
- Update imports: fixtures.tsx and main.tsx import from ./api (index)
- Use MizanContext instead of deprecated DjangoContext in examples
