Rename all djarea references to mizan

- djarea_clients.py → clients.py (both example apps)
- export_djarea_schema → export_mizan_schema (management command)
- djarea.spec.ts → mizan.spec.ts (playwright test)
- fetch.mjs: command name updated
- apps.py/asgi.py: import paths updated
- Removed stale generated.djarea.* artifacts
- Fixed desktop app: asgi.py import, vite config aliases, package.json dep path

373 Django tests pass. Both example apps verified running.
