feat(monitor/frontend): space weather panel (Kp 9-bar, solar wind, X-ray flux)

Three-row layout (label | value | secondary or 9-bar). Kp index renders as
a 9-segment grid bar — segments below kp filled --fg-2, at-or-above outlined
--fg-4. When kp >= 7 (G3+ geomagnetic storm) the entire filled portion goes
amber AND the panel's stale dot fires amber — one of the few legitimate
amber-data uses per ethos. X-ray class M or X also flips amber.

Backend snapshot caveat: the SWPC collector currently emits only
{ts, pushed} as the WS event payload — the actual kp / bz_gsm / speed_kms
/ density / xray_class / xray_flux readings live in Redis ring buffers
(per spec §6.2) but aren't yet projected into snapshot.space_weather.
The TS interface defines all fields optimistically; the panel renders
"—" / empty 9-bar for missing fields. When the backend extends the SWPC
event payload (or a separate snapshot enrichment lands), the panel
auto-fills with no frontend changes.

KP_SEGMENT_KEYS is an explicit string array instead of Array.from(...,
i) to avoid biome's noArrayIndexKey warning while preserving the
positional segment semantics.

Plan 5 Task 20 Design QA: Kp bar uses ONLY --fg-2 / --fg-4 / --amber
(no other colors), values mono tabular, X-ray class letter sans, no
sun glyph / aurora photo / weather-forecast iconography.
