Create the authenticated user's redacted corporate legal report

Account and credit-entitlement surface for a legal entity only. The server owns beta/pricing policy and a daily idempotency key scoped to user, company and UTC date; clients cannot choose price or entitlement. Every report is recursively PII-redacted before egress. Documentary events and citations do not prove wrongdoing, solvency, current status, identity of a natural person or completeness, and this informational report is not legal advice or an official certificate. Unknown or unauthorized source policy, natural-person subjects and missing helpers fail closed. The JSON body is capped at 32 KiB and accepts only the CSRF fallback.
