- Device dropdowns (quick-assign, bulk install, assign page) now only show devices with free slots; full devices are excluded entirely - New ChargeLog model tracks charge dates with optional cycle increment; battery detail page gets a Charge History card with add/delete rows - Device list page gets per-device Unassign All button (with confirmation) via new POST /device/<id>/unassign-all route
