Restore parent module guards for child components

[Copilot]

Dedicated child components now retain lazy module registration while targeting their parent component modules instead of redundant child modules.

• Parent module registration
  • Replaced child Igb*Module guards with the corresponding parent module across card, carousel, dropdown, list, nav drawer, rating, select, slider, stepper, tile manager, button group, and tree children.
  • Preserves the existing IsLoadRequested/Register lazy-loading pattern.

if (!IgbCardModule.IsLoadRequested(IgBlazor))
{
    IgbCardModule.Register(IgBlazor);
}
