fix(config): flatten platform fee config fixedFee to a plain integer amount

[jacklatourette]

The fixed fee currency is always implied by the fee config's sourceCurrency,
so the nested CurrencyAmount object was redundant. fixedFee is now the amount
in the smallest unit of the source currency.

Show sample

• PATCH /config — the feeConfigs/items/fixedFee request property's min was set to 0.00 [request-property-min-set]. This is a warning because sometimes it is required to be set. But good clients should be checked to support this restriction before such change in specification.
• PATCH /config — removed the request property feeConfigs/items/fixedFee/amount [request-property-removed].
• PATCH /config — removed the request property feeConfigs/items/fixedFee/currency [request-property-removed].

Greptile Summary

Updates the platform fee configuration contract to represent fixedFee directly as a nonnegative smallest-unit integer.

• Replaces the nested CurrencyAmount reference in the source FeeConfig schema with an int64.
• Regenerates the root and Mintlify OpenAPI bundles, preserving the remaining Currency and CurrencyAmount references.

Confidence Score: 5/5

The PR appears safe to merge, with the source schema and both generated bundles consistently representing the intended flattened fee amount.

The changed contract is applied consistently, the integer constraints match existing smallest-unit monetary conventions, and the generated bundle reordering preserves all remaining shared-schema references.

Important Files Changed

Filename	Overview
openapi/components/schemas/config/FeeConfig.yaml	Changes fixedFee from a currency-bearing object to a nonnegative int64 whose currency is implied by sourceCurrency.
openapi.yaml	Correctly reflects the source schema change in the generated OpenAPI bundle; relocated shared schemas remain present and referenced.
mintlify/openapi.yaml	Remains synchronized with the root generated bundle for local Mintlify API-reference rendering.
