Extract shared editor CSS and fix vehicle nav spacing

Move duplicated preview, spinner, navigation, and side-button styles
from VehicleEditor, ActorEditor, and PlantEditor into a shared
editor-common.css. Standardize class names (nav-index, nav-name,
side-btn) and fix VehicleEditor part-info min-width (100px → 150px)
to match the other editors.
