Add company legal name field to umaaas api

[matthappens]

Thunes requires legalName from the sender when it's a business sender

{
    "code": "UNRECOGNIZED_MANDATORY_COUNTERPARTY_DATA_KEY",
    "reason": "Unrecognized counterparty field name companyLegalName"
}

this exists as UmaCounterpartyDataField.COMPANY_LEGAL_NAME, but how no corresponding CustomerInfoFieldName

Greptile Summary

Adds COMPANY_LEGAL_NAME to the UserInfoFieldName enum in both openapi.yaml and mintlify/openapi.yaml to support the Thunes requirement for a legal company name when the sender is a business. Both files are kept in sync with the same one-line addition.

Confidence Score: 5/5

Safe to merge — minimal, additive enum change with no breaking impact on existing consumers.

The change is a pure addition to an open string enum. Existing values and references are untouched, and both spec files are updated consistently.

No files require special attention.

Important Files Changed

Filename	Overview
openapi.yaml	Adds COMPANY_LEGAL_NAME to the UserInfoFieldName enum, enabling the field to be used in CounterpartyFieldDefinition and PlatformCurrencyConfig required-fields arrays.
mintlify/openapi.yaml	Identical change to the Mintlify docs copy of the spec — COMPANY_LEGAL_NAME added to UserInfoFieldName enum to keep the two files in sync.
