feat(phase-14): redesign Test Detail page with Red/Blue tabs and dual validation (T-115, T-116, T-117, T-118)

T-115: TestDetailHeader with progress bar, contextual action buttons, and dual validation indicators

T-116: TeamTabs component with Red Team, Blue Team, Summary, and Timeline tabs

T-117: Redesigned TestDetailPage integrating new components with react-query mutations, toast notifications, and role/state-based permissions

T-118: ValidationModal for dual Red Lead / Blue Lead approval with required notes on rejection
