fix(ci): use SOP_TIER_CHECK_TOKEN for qa/security review gates — unblocks #899

RFC_324_TEAM_READ_TOKEN was never provisioned. Fallback
secrets.GITHUB_TOKEN is repo-scoped and cannot probe
/teams/{id}/members/{username} — Gitea returns 403 for
non-team-members. All open PRs fail qa-review and
security-review gates permanently.

Use the already-provisioned SOP_TIER_CHECK_TOKEN as
primary. It is used successfully by sop-tier-check.yml
which also probes team memberships via the same API
endpoint — same scope (read:repository + read:organization).
