Import Grafana dashboard JSON

[clushie]

etop currently builds dashboards from detected exporter metrics. It does not import Grafana dashboard JSON.

This proposal is for importing a documented subset of dashboard panels into the terminal UI. The design would need to identify supported panel types and query expressions, report unsupported parts clearly, and explain when a Prometheus backend is required.

Upvote this discussion to vote for this feature. Which panel types, variables and query patterns would you want to reuse? A minimal synthetic dashboard would help define a useful first version.

This is a feature proposal, not an implementation or a release commitment.
