chore: drop unused local bindings

Remove locals that are assigned but never read: two unused
JulianDate.now() calls in the flights and military nearby queries, an
unread record lookup in the military snapshot renderer, unused axes from
the CCTV gizmo, an unused vessel state alias, and two unused ALPR
presentation handles. Each removed expression is side-effect free.
