fix(labels-controller): update color validation to use WorklenzColorShades for label updates

- Modified color validation logic in `updateLabel` method to check against `WorklenzColorShades` instead of `WorklenzColorCodes`.
- Ensured that the color input is validated correctly during label updates, enhancing data integrity.
