feat(core-api): compose dsrRouter + consentRouter into appRouter

Add @repo/core-dsr and @repo/core-consent as dependencies and wire
dsrRouter + consentRouter into appRouter via the existing router
composition pattern. Integration tests cover all eight procedures
(dsr.export, dsr.delete, dsr.rectify, dsr.restrict, consent.grant,
consent.withdraw, consent.isGranted, consent.getCategories) with auth
and response-shape assertions.
