ionis__current_conditions returns SFI/Kp unavailable (SWPC JSON format drift, same as solar-mcp)

[KI7MT]

Diagnosis

Similar to solar-mcp issue #3: ionis__current_conditions (and related band outlook in reports) shows:

SFI: unavailable
Kp: unavailable
...
Note: Some data unavailable — Kp: 1

While solar wind and alerts populate.

Root Cause

In src/ionis_mcp/noaa.py:fetch_current_conditions():

• SFI: assumes if isinstance(data, dict) for /10cm-flux.json → now list → skipped.
• Kp: assumes list-of-lists latest[1] for /noaa-planetary-k-index.json → now list-of-dicts → KeyError caught as error.
• Bz: same for /summary/solar-wind-mag-field.json → list now.

The _fetch_json succeeds, but parse fails silently into errors list.

Duplicated logic from old solar-mcp client (before the fix there).

Solution (on branch)

• Updated parsing in noaa.py for current list-of-dicts + legacy fallback for all three endpoints.
• Verified: now sfi=128, kp=0.67, bz=-1, errors=[], full report with bands.

Related

• Same upstream change as solar-mcp.
• ionis current_conditions should perhaps delegate to solar-mcp for consistency in future, but this makes it work now.

PR to follow.
