Remove unnecessary components / html elements

[madhaven]

When the app was converted from Vanilla HTML to Angular, a lot of the design elements and tags were imported as is.
In effect, most components have an angular component decoration within which the HTML elements sit.
This can be confusing at times when it comes to the css decorators involved and the HTML structure

Reduce the unwanted HTML elements and move their importance to the host component.
Use :host decorators from Angular to migrate the CSS classes involved.
