Merge M1: org, board, access, audit + shadcn UI

Brings the M1 milestone to main: Identity/RBAC + JWT, OrgBoard board+cartable, Governance audit, the edit-distance metric, and the shadcn UI on the TeamUp design language. Verified green: dotnet build (warnings-as-errors), ArchitectureTests 8/8, IntegrationTests 20/20 (Testcontainers + real pgvector), client npm build, and a live stack smoke (SPA + API served, bootstrap→board flow 200).
