Explanation
Intent based swaps fees are already considered in sent amount. As the solvers take care of fees internally on provider side.
The current sent amount logic does add fees again in the calculation and shows larger amount than the actual amount sent.
This PR skips the fees from sent amount calculation logic resulting in correct amount.

Changes the
calcSentAmountcomputation used in quote metadata, which can affect displayed wallet deduction and downstream balance/fee calculations for intent-based swaps. Scope is small and covered by a targeted new unit test, but it touches core quote math.Overview
Prevents
calcSentAmountfrom double-counting protocol fees on intent-based swap quotes by skippingfeeDataaggregation when a quote includesintent(treatingsrcTokenAmountas already fee-inclusive).Adds a unit test covering an intent-based (e.g. CoW) quote case and records the fix in the
