fix(ui): project status convention, linked-order chip, diacritics, lazy dashboard

- PROJECT_STATUS added to documentStatus.ts (aktivni=info, dokonceny=success,
  zruseny=error — app convention); Projects/ProjectDetail local maps deleted;
  status Select derives its MenuItems from the shared map.
- ProjectDetail linked-order status now rendered via the received-order map
  (was the project map with zero key overlap → raw DB token).
- Cancelled label unified across received/issued orders in documentStatus.ts.
- 'Chyba pripojeni' → 'Chyba připojení' (Dashboard, AuthContext).
- Dashboard lazy-loaded like every other route — its 7 subcomponents leave
  the Login critical path.
