Migrate cards from Material-UI to @backstage/ui Card system#1445
Conversation
Create a new InfoCard component in ui-react using @backstage/ui primitives (Card, CardHeader, CardBody, CardFooter, Text, Flex) to align with upstream Backstage's migration away from Material-UI based InfoCard. Migrate all 14 usages across gs and flux-react plugins to the new component.
Replace direct Material-UI Card+CardContent usage with the new InfoCard component in ClusterToolsCard, DeploymentToolsCard, ResourcesCard, and GitOpsCard for consistent card styling across the application.
Replace Material-UI Grid, Switch, FormGroup with @backstage/ui Flex, Grid.Root, and Switch components. Simplify AboutField by removing gridSizes prop and using plain div instead of Grid item.
