feat: calculate swap impact for unsponsored oft/cctp swaps

[ashwinrava]

Backend changes:

• Added simulateMarketOrder calls to get input/output based quotes for:
  • Unsponsored USDC to USDT-SPOT
  • Unsponsored USDT to USDC-SPOT
• Used actual estimated output to calculate accurate swap impact
• Updated getTotalFeeUsd for cctp and oft providers to not directly return bridgeFeesUsd

Frontend changes:

• Added isHyperCoreSwap condition to display swap impact for:
  • Unsponsored USDC to USDT-SPOT
  • Unsponsored USDT to USDC-SPOT
• Removed unsponsored swap flows from restricted routes

Testing:
Unsponsored USDC to USDT-SPOT: (exact input)

Unsponsored USDC to USDT-SPOT: (min output)

Unsponsored USDT to USDC-SPOT: (exact input)

Unsponsored USDT to USDC-SPOT: (min output)

This works great for input-amount based swaps 💪 But we need a few more changes for output-amount flows

[ashwinrava]

@dohaki Thanks for the review and suggestions! I addressed your comments, used your commit's changes, and also modified the OFT strategy to get the bridge quote after calculating the required input for output based flows. That was missing in my previous revision. Here is the commit with the changes: 5ed9559

The screenshots show a negative swap impact for the OFT flows because I think the USD price for USDC-SPOT is a bit different than what we get for USDT0.

Nice 🔥
