feat(ui): Enhance contact page and add location flag to footer

This commit introduces several UI improvements to enhance user experience and visual appeal.

On the contact page, a new heading "Unlock Your Growth Potential" and a descriptive subheading have been added above the form. This provides better context and a stronger call-to-action for users.

In the footer, the location information now includes a flag icon for better visual identification. This was achieved by updating the `ContactInfo` component to accept an optional icon source.

Additionally, various styling adjustments have been made for improved responsiveness and visual consistency across the homepage and footer.
