Note

Replaces exchangeAmount with new amountQuery (exact/max/maxExchangeAmount) across UI and ramp plugins, adding crypto-amount and robust MAX flow support (with caps) notably for Infinite.

• Types/Core:
  • Replace RampQuoteRequest.exchangeAmount with amountQuery using RampQouteAmount (exchangeAmount | max | maxExchangeAmount).
  • Update all providers to consume amountQuery; remove references to RampExchangeAmount.
• UI (src/components/scenes/RampCreateScene.tsx):
  • Migrate state and logic to amountQuery; adjust initial amount, MAX handling, and navigation auto-advance for max.
  • Rework display amount calculations, insufficient funds checks, and button/quote enablement to use amountQuery and maxExchangeAmount.
• Providers:
  • Infinite (infiniteRampPlugin.ts):
    • checkSupport now reports supportedAmountTypes: ['fiat','crypto'].
    • fetchQuotes supports fiat/crypto amount types, MAX and capped MAX, validates against min/max, and builds source/target params accordingly; maps response amounts safely; updates dev test path.
  • Banxa/Moonpay/Paybis/Revolut/Simplex:
    • Read amountQuery (exchangeAmount/max/maxExchangeAmount) for quotes; apply appropriate limit checks and MAX-cap logic.
• Misc:
  • Minor guard/derivation updates (e.g., rate display gating, max-quote picking) to align with new amount model.

@swansontec I'm okay with removing some of the refactor for staging and instead punt it to develop if you don't think its safe enough

One AI comment should be looked at, but overall this is a good improvement.
