feat(monitor/frontend): ISS panel (live position + next-pass placeholder for phase 6)

Four-row layout: Lat/Lon (degree symbol, mono), Alt (km, mono tabular),
Vel (km/h with thousands separator, mono tabular), Next Pass (— stub).

Reads snapshot.iss_position directly (no per-panel store — current
position is the only thing the panel cares about, and the wheretheiss.at
collector pushes a complete state every 10s, so latest-event semantics
match what the panel needs). Real shape verified: latitude/longitude/
altitude/velocity/timestamp/fetched_at — all numeric except fetched_at
ISO string. Stale threshold 30s (3x the 10s poll cadence).

Next Pass row stays "—" muted --fg-3 — Phase 6 wires the SGP4-driven
user-observer-location pass prediction per spec §10.4. No "sign in to
add observer" CTA: operator UI doesn't onboard.

Plan 5 Task 21 Design QA: degree symbol + mono coords, alt/vel mono
tabular, no decorative ISS-tracing widget (the centerpiece globe owns
that), next-pass row visible-but-muted (never hidden).
