Lift the header (IP, country tag, traversal badge, identity badge)
into its own section component. Tag helper moves to a shared
AttackerDetail/ui.tsx so future sections can reuse it without
re-importing through AttackerDetail.tsx.
- New AttackerDetail/sections/AttackerHeader.tsx (~50 LOC)
- New AttackerDetail/ui.tsx for shared presentational helpers
- AttackerDetail.tsx imports both; local Tag definition deleted
- AttackerHeader.test.tsx covers country present/absent,
TRAVERSAL badge, IDENTITY click-through, identity null path
