Techniques don't have their own Jira tickets — tickets exist on tests
and campaigns. The previous JiraLinkPanel entityType='technique' always
returned empty.
Backend: add entity_ids (list) filter to GET /jira/links so multiple
test IDs can be fetched in a single request.
Frontend API: listJiraLinks() accepts entity_ids[] and serialises them
as repeated query params (required by FastAPI List[UUID] parsing).
TechniqueDetailPage: replace JiraLinkPanel with TechniqueJiraSection —
a dedicated read-only component that:
- Takes technique.tests (already loaded)
- Batch-fetches all test Jira links in one request
- Shows test name + ticket key + status + priority + open-in-Jira link
- Hides itself when no tickets exist (avoids empty panel)
