fix(jira,evidence,tempo,settings): 4-issue fix batch

Jira — PoC custom field:
- Add customfield_10309 (Proof of Concept) to issue fields when creating
  test tickets so the attack procedure appears in the dedicated Jira field

Tempo — blue team exclusion:
- Remove blue_team_evaluation from _TEMPO_ACTIVITY_TYPES; blue team time
  is tracked internally (worklogs) for SLA but never sent to Tempo since
  blue team has no Jira access

Evidence — uploaded_at NULL fix:
- Set uploaded_at=datetime.utcnow() explicitly in upload_evidence router;
  the DB column has no server default so it was saving as NULL

Evidence — presigned URL browser access:
- Add MINIO_PUBLIC_ENDPOINT setting (config.py, docker-compose.prod.yml)
- storage.py uses a dedicated _public_client for presigned URL generation
  so browsers receive URLs with the publicly accessible hostname instead of
  the internal Docker service name (minio:9000)
- Expose MinIO port 9000 in docker-compose.prod.yml

Evidence — Jira attachment:
- After upload to MinIO, call jira.add_attachment() to attach the file to
  the linked Jira ticket (non-fatal; errors are logged and swallowed)

Settings — hide Jira/Tempo from blue team:
- ProfileSection checks user role; blue_lead and blue_tech do not see the
  Jira Integration or Tempo Integration personal settings sections
