Assign a plan to an account and propagates it to every store under that account: existing active/expired store_plans are closed and a fresh active store_plan (running to month-end) is created per store, and the account-level company_plans link is updated/created.

Auth: Partner — authentication under partner/account. Path id must resolve to a bundle_id=3 company (404 if missing, 403 if not an account), with a partner (getParentCompany) and pass canManageBrand else 403. The plan must be available to that partner via company_plans, and must match the partner billing model: plan-based partners may only assign is_admin_managed=1 plans. Usage-based partners only is_admin_managed=0 (else 403).

Rate limit: No rate limit.
