Stretch sky view to fill right column height

- command-rail last row changed from minmax(260px, 340px) to 1fr so the
  polar plot expands to fill whatever vertical space remains after the
  Next Pass and Live Telemetry panels
- polar-container made flex-column so panel-content can grow with flex: 1
- #polarPlot width/height 100% with aspect-ratio 1/1 — canvas fills the
  available square area and stays proportional
- Remove align-items: start from the 1320px breakpoint primary-layout so
  the command-rail stretches to match map height in the two-column layout
- Fix matching 2-column command-rail rows at 1320px breakpoint
