This commit addresses issues with the tree view not fully utilizing the
available width (appearing squeezed on the left) on bigger screens, and
inconsistent padding during searches.
The changes centralize padding and script tree rendering logic to
enforce consistency and prevent regression.
Changes:
- Fix tree view width utilization.
- Refactor SCSS variables for better IDE support.
- Unify padding and tree background color logic for consistent padding
and coloring around the tree component.
- Fix no padding around the tree in tree view.
- Centralize color SCSS variable for script background for consistent
application theming.
