Fix App Bar Icon Shrinking and Wrapper Overlapping with main contents Issues

[rajveeerr]

PR Fixes:

• Fixed app bar icon sizing by setting the min-width to 3.7rem (previously, the width was set to 4vw with no min-width), leading to icons shrinking to an unusually small size.
• Increased padding in the wrapper to resolve the overlapping issue between the app bar and buttons.
