feat(tests): auto-propose procedure suggestions from submitted rounds, add lead review workflow

When Red or Blue submits a round for a test created from a template,
any extractable command in their procedure text is proposed as an
update to the template's suggested procedure — never written
automatically. Adds GET/approve/reject endpoints scoped so a lead only
reviews their own team's suggestions; approving writes the suggested
text into the template, rejecting leaves it untouched.
