gui: add checkable constellation legend to filter sky plot by GNSS system

Browse Source 
Replaces the static painted legend with real checkboxes (one per
GNSS system, color-swatched to match GNSS_COLORS) so users can
toggle which constellations show in the sky plot and satellite
table, mirroring the existing receiver-source filter checkboxes.
