NodeGraph fails to display anything with Postgres datasource #78

Due to the following line, all edges and nodes are filtered from the fetched tables when using the Postgres datasource:

plutono/packages/plutono-ui/src/components/NodeGraph/useCategorizeFrames.ts

Line 11 in 9ea56e2

const serviceMapFrames = series.filter((frame) => frame.meta?.preferredVisualisationType === 'nodeGraph');

frame.meta?.preferredVisualisationType cannot be added in any way through the web application when fetching the data from Postgres, while it is present e.g. with the TestDB datasource.

See Grafana upstream:

https://github.com/grafana/grafana/blob/4e6a7121ed9267cdf637b55438aac2a6e7530532/public/app/plugins/panel/nodeGraph/utils.ts#L569-L576

Here the check is performed less aggressively and also considers that the data may come from a table where the refId describes the type of data (nodes or edges).
