feat(config): fee config fixedFee takes an amount and a currency code

[jacklatourette]

fixedFee is now an object of amount plus a plain ISO 4217 currency code,
so the fee currency is explicit without nesting the full Currency object.

Greptile Summary

The PR changes fixedFee from a source-currency integer to an explicit amount-and-currency object.

• Updates the modular FeeConfig source schema.
• Regenerates the root and Mintlify OpenAPI bundles with the new shape.
• Makes both amount and currency required when fixedFee is supplied.

Confidence Score: 4/5

This PR should not merge until the fixedFee wire-format break is placed behind the repository’s required API-version change.

The current platform configuration request and response contracts replace an integer with a required object, invalidating existing payloads and generated client types while info.version remains unchanged.

Files Needing Attention: openapi/components/schemas/config/FeeConfig.yaml and openapi/openapi.yaml

Important Files Changed

Filename	Overview
openapi/components/schemas/config/FeeConfig.yaml	Defines the new fixedFee object contract, but introduces a breaking type change without the required API version bump.
openapi.yaml	Correctly reflects the source-schema change in the generated public bundle, including the unversioned breaking contract.
mintlify/openapi.yaml	Remains synchronized with the root generated bundle and exposes the same breaking fixedFee shape to documentation consumers.

Prompt To Fix All With AI

### Issue 1
openapi/components/schemas/config/FeeConfig.yaml:19-21
**Unversioned fixed-fee type break**

When existing clients send an integer `fixedFee` to `PATCH /platform/config` or deserialize it from `GET /platform/config`, the changed schema replaces that value with a required object, causing request validation or generated-client type failures without the required API-version boundary.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.
