Add order management UI

Rebuild the landing page as an order overview for the Speisekarte24 tool:

- Two tabs: all orders and "Nicht übermittelt", the latter fed by the
  15-minute rule and highlighted while it holds entries
- Table, list and grid views behind an icon dropdown, plus search,
  filters, sorting and pagination
- Escalation timeline (three transmissions, tag, voice message, direct
  call, SOS) rendered in the detail dialog, inline in the list view and
  condensed to the current step in the table
- Action definitions live in one module and feed the row menu, the
  detail dialog and the card quick-action bar
