fix(capital): address PR #154 review — proper interface instead of as-cast, IInput['data'] canon

document-domain.service.ts: replaced the inline `as Cooperative.Document.IGenerate & {...}`
hack with a dedicated GenerateDocumentWithPrivateDataDomainInterface for the doc_data
pre-generation branch (Cooperative.Document.IGenerate already carries a `[key: string]: any`
index signature, so the narrow interface is assignable without any cast at all).

Onboarding api/index.ts: saveProgramDocDataHash now takes
Mutations.Capital.SaveCapitalProgramDocDataHash.IInput['data'] and forwards it as-is to
variables.data, matching the SDK IInput['data'] canon used by completeStep right above it
instead of taking a bare string and rebuilding the payload inline. Updated both call sites.
