feat: addition of a button below existing one for the routing to the …

[owens-hub-git]

Description

Strict frontend change in the home component where I added a button underneath the current view all for previous units. This still routes to the same component for previous units, but will be the start for the cross-unit dashboard development

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

1. Run the project locally.
2. Opened the HomePage as a student
3. Changing layouting for responsiveness and routing
4. npm test locally

The dashboard button should be above the history button as it would generally be more important.

Suggested change

	aria-label="view all projects"
	aria-label="view previous projects"

Suggested change

	<mat-icon style="color: white">history</mat-icon> View all
	<mat-icon style="color: white">history</mat-icon> View previous

Should be changed so it's distinct from the other button.
