- GET /api/instances now accepts ?sort= (name|vmid|created_at|updated_at)
and ?order= (asc|desc); invalid sort fields fall back to name asc
- Timestamp sorts use id as a tiebreaker (datetime() precision is 1 s)
- Toolbar gains a sort-field <select> and a ↑/↓ direction toggle button
- toggleSortDir() flips direction and re-fetches; state held in data-dir attr
