SecurEye now properly follows moving cameras (#89507)

## About The Pull Request

Port of a fix from
https://github.com/Monkestation/Monkestation2.0/pull/4995

Due to how modular computers worked with the nested tgui stuff, the
SecurEye app wouldn't properly autoupdate whenever a camera it was
watching moved (when there's not any tracking going on)

This "fixes" that issue by adding a new var, `always_update_ui`, to
modular computer programs, which will make the modpc call the active
program's `ui_interact` even after the UI is opened.

## Why It's Good For The Game

bugfix good. if the whole "watch broadcast camera streams on PDA" thing
ever gets ported here, this is a needed fix for that.
