Link a BoM component (sub-product)

POST 
/api/v1/products/:id/components

Required scope: dpp:draft:write. A WRITE (HMAC + Idempotency-Key). A childProductId MUST be a product your company owns OR a publicly Approved DPP — a cross-tenant child returns 404 CHILD_PRODUCT_NOT_AVAILABLE (never 403). Max 50 components per product; self-reference and circular linkages (depth 5) are rejected.
