* fix: Remove mistaken red team UI from VN frontend

PR #39 accidentally added red team UI code to the wrong frontend directory
(frontend/ instead of makima/frontend/). The correct implementation is
already in makima/frontend/. This commit removes the mistaken changes:

- Delete ContractCreateModal.tsx (was added by mistake)
- Revert ContractList.tsx to remove red team badge and create modal
- Revert ContractDetail.tsx to remove red team tab and notifications
- Revert types.ts to remove contract/task types
- Revert pc98.css to remove red team styling
