Using the any provider scope for a configurable ThemeService

Let's use the any provider scope for a configurable ThemeService by injecting configurable settings depending on the use case for each module that we load:

@Injectable({
  providedIn: 'any',
})
export class ThemeService {
  constructor(@Inject(themeToken) private theme: ITheme) {}
  public setSetting(name: string, value: string): void {
    this.setItem(name, value);
  }
  public getSetting(name: string): string {
    switch (name) {
      case 'background':
        return this.getItem(name) ?? this.theme.background;
      case 'tileBackground':
        return this.getItem(name) ?? 
         this.theme.tileBackground...
