Some pages in the project doesn't have a favicon

## Is your feature request related to a problem? Please describe.
The homepage, sos page, and contact-us page have no favicon.

## Describe the solution you'd like
I'd like to add the favicon to those pages I mentioned. I don't think the favicons were omitted deliberately since it's on other pages.

## Additional context

### The About Us page

### The SOS Report page

### The Homepage
