Subject: [PATCH] feat(ms-ai-architect): renderer A.6 dpia adopt page-header +
 residual-pair

- parseMatrixRisk utvidet med residualPair-felt + _consumer-diskriminator (R15)
- Stotter "Restrisiko: AxB > CxD"-syntax (numerisk) og "Restrisiko: label > label" (fallback)
- Sesjon 4 vil sette _consumer='ros' nar Ros-spesifikk markdown oppdages
- renderDpia: matrix + residual-pair (B6) + threats-table, wrapped i renderPageShell (eyebrow DPIA)
- KeyStats utvidet med RESTRISIKO-stat nar residualPair eksisterer (modifier high hvis score>=9)
- Fixture dpia.md utvidet med "Restrisiko: 4x3 -> 2x2"-linje under Konklusjon
