fix: 4 improvements — campaign test deletion, review queue triggers, technique link, Jira read-only

1. Campaign test deletion: removing a test from a campaign now also
   deletes the underlying Test record and recalculates technique status.

2. Review Queue triggers: review_required=True is now also set when
   - Sigma/Elastic detection rules are imported for a technique
   - A test is validated (coverage status changes)

3. Test detail — Technique link: 'Technique' entry added at the top of
   the Details sidebar showing MITRE ID + name as a clickable link to
   /techniques/{mitre_id}.

4. Jira panel — read-only on test page: added readOnly + label props to
   JiraLinkPanel. TestDetailPage now passes readOnly=true and the test
   name as label, hiding Link Issue / Sync / Unlink controls (automatic
   Jira creation only — no manual management).
