Add borders and colors

**Is your feature request related to a problem? Please describe.**
Add borders/coloring to improve readability.

**Describe the solution you'd like**
Add borders around sections and add colors highlighting specific parts. The application already did a good job differentiating the important sections(title, summary and description) in a struct, leveraging these highlighting can be added without changing much of the code.

**Additional context**
The project already uses [Lip Gloss](https://github.com/charmbracelet/lipgloss) package. The mentioned improvements can be achieved by using the same package without adding any additional dependencies.
