feat(work-order-dashboard): PDF download in Docs tab + gate chat by config

- Documente tab: link to a new /app/work-orders/{id}/pdf route that
  streams the invoice PDF via WorkOrderPdfService; also lists any
  files uploaded to the 'signed_documents' media collection.
- Chat client card: only show the input form when telegram_bot or
  whatsapp_business is enabled AND credentialed in the tenant's
  Integrations page. Otherwise render an empty state with a shortcut
  to /app/integrations.

RU + EN translations added for the new strings (RO source).
