refactor(admin-v2): Consolidate compliance/DSGVO pages into SDK pipeline

Remove duplicate compliance and DSGVO admin pages that have been superseded
by the unified SDK pipeline. Update navigation, sidebar, roles, and module
registry to reflect the new structure. Add DSFA corpus API proxy and
source-policy components.
