Register GS1 company prefix(es) (closes the GS1 gate)

POST 
/api/v1/companies/me/gs1-prefixes

Required scope: dpp:draft:write. A WRITE (HMAC + Idempotency-Key). ADD semantics — the provided prefixes are merged into your company's existing set (deduped). Each prefix must be 4-12 digits. Registering at least one prefix closes the gs1_prefix_not_registered publish gate that otherwise blocks every paid-plan publish. Returns the resulting set.

422

A prefix is not 4-12 digits (GS1_PREFIX_INVALID).

429

429 — RATE_LIMITED (per-key limit, reads and writes alike; fails closed, so a limiter outage also returns 429). A limiter-down 429 is deliberately indistinguishable from a quota 429. Carries Retry-After (seconds).
