Atmos Alarm Control computer program search fix and UI refactor (#21056)

Scope creeped PR. Fixes a breaking bug in the Atmos Alarm Control
application introduced after areas-cleanup PR, but also refactors it
into a grid-based interface that actually allows you to reliably search
alarms by name, department, and deck # (possible now with all the area
metadata we have to play with).

Also does behind-the-scenes cleanup of alarm panel code in general, a
few area def problems, and some manually defined air alarm names on the
map.
