Fix vector and euler numeric input and make them reactive

[AidanCaruso]

Summary

• Adds a line to Vector3Input and EulerInput to set the value of a hookstate that the input value is later assigned to. This ensures numeric fields always register input.
• Updates components in scale/position/rotate editor control functions so input fields react to changes.
• Euler-input rotations are now only converted from quaternions when updated by editor control functions.
