Adds the second ionospheric data source layer. Polls NOAA SWPC's free public JSON services every 5 minutes for three products: * Planetary K-index (1-min cadence) → geomagnetic_observations * 10.7 cm solar flux (hourly) → solar_flux_observations * GOES X-ray flux (1-min, 0.1-0.8nm long-wave band only) → solar_xray_observations All three products feed HF / Es scoring inputs that the propagation engine will start using in a follow-up commit: * Kp drives HF absorption and Es damping (memory notes Kp is inversely correlated with tropo/Es stability). * F10.7 is the SSN proxy for ITU-R P.533 HF MUF prediction. * GOES X-ray long-wave flux is the short-wave fade (SWF) / D-layer absorption proxy — a C-class flare starts attenuating HF within seconds of the X-ray peak. New context `Microwaveprop.SpaceWeather` exposes `upsert_*/1` and `latest_*/0` per product; `SpaceWeatherFetchWorker` pulls all three independently so one endpoint's outage doesn't block the others. Fixtures captured from live SWPC endpoints on 2026-04-15 for the parser tests. Not yet wired into scoring — that's a separate commit.
