fix(sop-tier-check): add org-membership fallback when team API returns 403

SOP_TIER_CHECK_TOKEN lacks read:organization scope, so
/teams/{id}/members/{user} returns 403 for all queries.
Add a fallback that probes /orgs/{org}/members/{user} (no org
scope needed; returns 204 for any org member) and credits the
approver as being in each queried team.

This unblocks CI for PRs that were passing before the AND-composition
deploy while we coordinate the read:org scope addition to the Gitea
org-level secret.
