Revamp Frontend design and functionality

[harshit078]

Why do we need this ?

• Currently, our app seems to have inconsistent padding and margins to variable font sizes and selections across the UI making the UI inconsistent.

Currently

• There seems to be excessive padding on dropdowns and some dropdowns don't follow that padding

• When the app is loaded up, there seems to appear 3 loading states showing the progress. Having one progress should be enough

• Deployment Insights page has variable font sizes and selection and is overwhelming with texts.

• Most Cards are not fully optimised to take up the entire space and width and show the user better context.

• Teams Page cards could be improved with added styling, importing repository images/logo and showing more details

• System logs page could be improved with added styling and design preferences.

• Before

• After

• These changes along with Enhancing performance metrics #651 would make the Frontend a lot optimised for performance with better design and UX
