refactor(29561): Refactor the Edge overview panel

[vanch3d]

See https://hivemq.kanbanize.com/ctrl_board/57/cards/29561/details/

The PR refactors the Overview panel of the Edge node in the Workspace. It fixes a known bug when data is missing for the default reporting diagram (topic wheel).

It also expands the reporting power of the Workspace by adding several new diagrams to the panel. They are all experimental in nature and might - or might not - help identify aspects of the topology of the current Edge configuration:

• the Workspace Cluster diagram is a live visualisation of the clustering of workspace entities (adapters, device, bridge ) based on dynamic keys (such as by status, by type, with given topic in mappings, ...)
• The Concept Wheel is a dynamic visualisation of the segmentation of the concepts (topic, topic filters, tags) used in the Edge configuration, showing common branching and namespacing (and metadata of each aggregated segment)
• The Relation Chords diagram shows how concepts of the Edge configuration are connected to each other through relations (mappings and datahub policies)
• The Concept Flow diagram shows how concepts feed into each other through relations, identifying a common "pipeline" of data transfer.

All the diagrams are work in progress and are completely dependent on the variety and volume of the configuration data.

Out-of-topic

• Detection of a diagram "empty state" (e.g. not enough data to show meaningful data visualisation) depends on each chart and its customisation power. A simple rendering has been implemented for each but a more consistent approach will be part of a further ticket
• The addition of the data policies to the computation of the Edge ontology will be part of a further ticket
