Plugin frontend refactor changes

[satyambnsal]

Changes Summary

• Add path alias support
• Import variables naming changes
• Import statements order sanity (external library imports followed by local imports)
• Integrate Prettier with ESLInt for consistent formatting across all team member's devices
• Use custom hooks useAsync and useTimeout for async and timeout effects.
• Prefer using Named exports instead of default exports as you don't have to come up with a name when importing it.
• Code formatting changes.

I tested the code locally with the Payable and Greeter contracts and seems to be working fine.
