feat(wizard): add license lookup panel (UI mockup)

Add collapsible LicenseLookupPanel component to step 3
of the order wizard (left column). Panel queries mock
LicServer data by license key and displays product,
customer, dates, status badge and licensed modules.
Real API endpoint can replace mock in lookupLicense().
