feat(customers): require businessInfo when creating a business customer

[shreyav]

Summary

Makes businessInfo a required field when creating a business customer via POST /customers.

Previously businessInfo was optional on BusinessCustomerCreateRequest, even though the nested object already requires legalName, taxId, and incorporatedOn. A business customer can't be meaningfully onboarded without it, so this tightens the schema to reject requests that omit it entirely.

Changes

• openapi/components/schemas/customers/BusinessCustomerCreateRequest.yaml — add businessInfo to the required list on the business-specific allOf member. This applies only to the BUSINESS branch of the create request; individual customers are unaffected.
• Regenerated openapi.yaml and mintlify/openapi.yaml via make build.

make lint passes (only pre-existing, unrelated schema-properties-* warnings remain).

Note: info.version / servers.url are unchanged — the spec date-version tracks published API versions, and bumping it implies a new server path, which is a separate coordinated rollout.

Greptile Summary

This PR tightens the BusinessCustomerCreateRequest schema by adding businessInfo to the required list of the inline allOf member, ensuring the field cannot be omitted when creating a business customer via POST /customers. Both generated bundles (openapi.yaml and mintlify/openapi.yaml) are regenerated and in sync with the source change.

• Schema change (openapi/components/schemas/customers/BusinessCustomerCreateRequest.yaml): adds required: [businessInfo] to the inline type: object allOf entry that already defined the businessInfo property (referencing BusinessInfo, which itself requires legalName, taxId, and incorporatedOn). Individual customers and the update endpoint are unaffected.
• Documentation (mintlify/snippets/creating-customers/customers.mdx): the sentence "The only required field for all customers is customerType" is now inaccurate for BUSINESS customers and should be updated to reflect the new requirement.

Confidence Score: 4/5

Safe to merge; the schema change is minimal, correct, and both generated bundles are in sync. One doc snippet carries a now-inaccurate claim about required fields for business customers.

The schema change itself is correct and well-scoped. The only gap is that mintlify/snippets/creating-customers/customers.mdx still says 'The only required field for all customers is customerType', which contradicts the newly enforced businessInfo requirement for business customers and could mislead integrators.

mintlify/snippets/creating-customers/customers.mdx — the customer-type requirements description needs updating.

Important Files Changed

Filename	Overview
openapi/components/schemas/customers/BusinessCustomerCreateRequest.yaml	Adds required: [businessInfo] to the inline allOf member that already defined the businessInfo property; change is minimal and correctly placed.
openapi.yaml	Generated bundle that correctly reflects the source schema change — required field added to BusinessCustomerCreateRequest's inline allOf member.
mintlify/openapi.yaml	Mintlify-specific generated bundle; identical change to openapi.yaml, both are in sync.
