fix(spec): constrain namespace, website, and SSL status enums

[pcfreak30]

Syncs swagger.yaml to the live service spec and regenerates the client.

Adds enum constraints for domain/gateway/DANE namespace (icann, hns),
domain status (draft through onchain_managed), and SSL status (pending,
issuing, ready, failed). Codegen now prefixes the upload status enum
constants, so internalclient.Completed becomes
internalclient.UploadResultResponseStatusCompleted, and the SSL status
field is a named type; wrapper updates and test adjustments follow.

---

This PR syncs the SDK with the API specification by constraining several string fields to enums in the generated client code. Specifically:

• Domain namespace and domain status fields in DomainDANERepublishResponse and DomainResponse are now typed enums with allowed values (icann/hns for namespace, and draft, records_generated, waiting_delegation, active, self_hosted, error, onchain_managed for status).
• SSL status in SSLStatusInfo is now an enum with values pending, issuing, ready, failed.
• The OpenAPI spec (swagger.yaml) was updated to include these enum constraints, keeping the spec and generated client in sync.
• Upload status constants were renamed to be prefixed with the enum type name for consistency.
• Tests were adjusted to use string conversion where enum values are compared, and a call site in websites.go now explicitly casts the enum to a string when returning.

This change strengthens type safety, prevents invalid values from being sent or received, and ensures the SDK adheres to the official API contract.
