fix(gate): review-check 403 hard-fail → continue; add /sop-n/a N/A gate

- review-check.sh: 403 on team-probe now continues/skip instead of
  exiting 1. Token owner not in team (mc#1111) is a known gap; skip
  the candidate and check the next. Fail closed only when ALL candidates
  are exhausted.
- sop-checklist.py: implement /sop-n/a directive parsing and
  na-declarations status posting (RFC#324 §N/A follow-up). Posts
  \`sop-checklist / na-declarations (pull_request)\` status so that
  review-check.sh can waive qa-review/security-review Gitea-APPROVE
  requirement when a valid team member has declared N/A.

Blocks: #1233, #1229, #1255, #1257, #1259, #1260 (qa/sec hard-fail
403 preventing those PRs from advancing).
