• Fix Rangefinder of NATO Laser Designators works differently from CSAT's #10336 by uniforming Laser Designator behaviour.
  Since many modern PLDs are marketed with an eye-safe RF, and designation lasers generally not being eye-safe, it follows that the 2 features are independent from one another.
  • The NATO Laser Designator would previously only rangefind while designating, with the rangefinding feature via the "T" keybind being disabled. Now both functionalities work independently.
  • The CSAT Laser Designator would previously rangefind independently, but not update the range indication while designating. Now it does both, working the same as the NATO designator.
    I also added the laser code indicator that was previously only implemented on the NATO designator. It would look more in line with the baseline UI with a box around the laser code, but my GUI modding abilities are insufficient (feedback appreciated).
