feat(sdk): Replace mock data with real API calls in consent, DSR, and consent-management

- /sdk/consent: Replace hardcoded mockDocuments with GET /api/admin/consent/documents
- /sdk/dsr: Replace createMockDSRList with fetchSDKDSRList via /api/sdk/v1/dsgvo/dsr
- /sdk/dsr/new: Replace console.log mock with real POST to create DSR requests
- /sdk/dsr/[requestId]: Replace mock lookup with real GET/PUT for DSR details and status updates
- /sdk/consent-management: Add real stats, GDPR process counts, and email template editor
- lib/sdk/dsr/api.ts: Add transformBackendDSR adapter (flat backend → nested frontend types)

Prepares for removal of /dsgvo and /compliance pages.
