fix(trivy): use official Aqua Security Trivy logo as icon source

The authoritative icon source containers/trivy/trivy.svg held a generic
hand-drawn shield/magnifier placeholder, while the frontend copy had the
official brand mark. The icon sync (webuiSyncAppIcons) treats the source as
canonical, so it was clobbering the official logo with the placeholder on
every full WebUI update/install — leaving the setup wizard's app tile
showing the generic icon. Replace the source with the official logo so it
sticks.
