Handle standardized sensors_to_show plots in flexmeasures show asset

[Copilot]

flexmeasures show asset --id <asset_id> crashed with KeyError: 'sensors' when sensors_to_show used the standardized schema (title + plots). The CLI deserialized to the new structure but still rendered the legacy top-level graph["sensors"] shape.

• CLI output path now supports standardized schema

  • Replaced legacy rendering in show_generic_asset with _format_sensors_to_show(...).
  • Formatting now iterates graph["plots"] and renders supported plot variants:
    • {"sensor": ...}
    • {"sensors": [...]}
    • {"asset": ..., "flex-model": ...}
    • {"asset": ..., "flex-context": ...}

• Resilient fallback behavior

  • Unexpected graph/plot shapes no longer crash rendering.
  • Unknown plot payloads are stringified for visibility instead of raising.

• Regression coverage for CLI rendering

  • Added coverage for standardized plots-based sensors_to_show output.
  • Added direct formatter coverage for asset/flex-* plot references and unknown plot dictionaries.

def _format_sensor_plot(plot: dict) -> str:
    if "sensor" in plot:
        return str(plot["sensor"])
    if "sensors" in plot:
        return str(plot["sensors"])
    if "asset" in plot:
        asset_text = f"asset={plot['asset']}"
        reference_keys = [
            f"{key}={plot[key]}"
            for key in ("flex-model", "flex-context")
            if key in plot
        ]
        return f"{asset_text} ({', '.join(reference_keys)})" if reference_keys else asset_text
    return str(plot)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• publicsuffix.org
  • Triggering command: /home/REDACTED/work/flexmeasures/flexmeasures/.venv/bin/pytest pytest (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
