Retrieve the full details of a submitted business formation order — contact, address, company info, register-agent details, processing status, and case-progression metadata.

Async population caveat: the parent order record commits immediately on POST /create-order, but child relationships (contact, businessAddress, companyInfo) are linked via async triggers in CorpNet's underlying Salesforce backend. There is a brief window — seconds to minutes — where this endpoint may return null for fields the spec marks required. Workflow-phase-dependent fields (orderFilingType, filedDate, formedEntityId) stay null until the order phase advances past Order Received. If you need a complete read, retry after ~30 seconds.

required semantics: in this endpoint's response schema, fields marked required are required as part of the documented contract, not guaranteed populated on every read. The two meanings are different — see the async-population note above.
