fix(app-graph): show edges for resources referenced via properties

[Copilot]

The getGraph API only creates connection entries from properties.connections and properties.routes. Resources referenced via arbitrary properties (e.g. secretName: dbsecret.name) appear as isolated nodes despite being in the same application graph.

Changes

• graph.ts — Added properties?: Record<string, unknown> to Resource interface.

• ApplicationTab.tsx — After fetching the graph, calls radiusApi.getResourceById() in parallel for each resource to enrich it with its full properties. Failures are caught and logged; the graph still renders without them.

• AppGraph.tsx — Added collectPropertyRefs(): recursively scans resource.properties for string values matching the ID or name of another resource in the graph. Matched refs that aren't already explicit connections are rendered as dashed edges (strokeDasharray: '5,5'). Skips application, environment, provisioningState, and status keys to avoid spurious edges.

resource postgresql '...' = {
  properties: {
    secretName: dbsecret.name  // now renders a dashed edge postgresql → dbsecret
  }
}

Screenshots

Before: dbsecret appears as an isolated node with no link to postgresql.
