Sentry turrets - Part 4: The sentry turret and its primary systems (#35123)
* Initial commit * Removed mention of StationAiTurretComponent (for now) * Prep for moving out of draft * Fixing merge conflict * Re-added new net frequencies to AI turrets * Removed turret control content * Removed unintended change * Final tweaks * Fixed incorrect file name * Improvement to fire mode handling * Addressed review comments * Updated how turret wire panel auto-closing is handled * Ranged NPCs no longer waste shots on stunned targets * Fixed bug in tracking broken state * Addressed review comments * Bug fix * Removed unnecessary event call
