fix(ci): add jq install to review-check-tests workflow + fix /tmp/jq hardcode

Two fixes found during first CI run:

1. Workflow missing jq installation step — T12 jq-filter test needs jq
   which is not in the Gitea Actions ubuntu-latest runner image.
   Add the same install dance as sop-tier-check.yml (apt-get first,
   GitHub binary download fallback, infra#241 belt-and-suspenders).

2. test_review_check.sh hardcodes /tmp/jq in T12. In CI jq gets
   installed to /usr/bin/jq via apt-get. Fix: use `command -v jq` to
   resolve from PATH first, fall back to /tmp/jq for local dev.
