ux: Implement dynamic Price Impact color warnings

[AlAfiz]

Description

Users don't always read the small text for Price Impact when executing a trade. We need to use color psychology to warn them of bad trades.
The percentage text should dynamically change color based on how severe the impact is.
This gives instant, peripheral visual feedback that a trade might be dangerous.
It is a standard DeFi feature that prevents angry users from losing funds to slippage.

Requirements

• Locate the "Price Impact" display inside the main Swap card component.
• Add logic to check the priceImpact value.
• If < 1%, apply a green Tailwind class (text-emerald-400).
• If >= 1% and < 3%, apply a yellow warning class (text-yellow-400).
• If >= 3%, apply a bold red danger class (text-red-500).
