Get a gateway policy
Returns a single gateway policy by id. Cross-org access is rejected with 404
Spend tracking: spend-cap policies include
current_spend_usd for the active window so callers can
read per-policy cost without hitting a separate endpoint.
Guard policies leave it null.

OK
CurrentSpendUSD is the spend in the policy's current window. Set for any spend_cap policy regardless of enabled state — disabled policies still surface usage so users can see what would have been counted. Nil for non-spend_cap policies or when the spend lookup failed.
ParentPolicyID is set on materialized children of a default_spend_cap to the default's id, and cleared (NULL) only when an admin Create with the same matchers takes over the materialized row. Update on a child preserves the link; Delete on the parent cascade-soft-deletes every child rather than detaching them.
