feat(dashboard): complete frontend redesign for Issue #271

- +layout.svelte: Upload button in header (authenticated users only)
- +page.server.ts: call /api/dashboard/resume, /pulse, /activity;
  remove deprecated /api/documents/incomplete and /recent-activity
- +page.svelte: 2-col grid layout (main + 320px sidebar), greeting,
  DashboardFamilyPulse + DashboardActivityFeed in sidebar
- DashboardResumeStrip: refactored to use server data (resumeDoc prop),
  SVG thumbnail, progress bar with aria-*, empty state, CTA
- DashboardFamilyPulse: new component — weekly stats from audit_log
- DashboardActivityFeed: new component — activity feed with "für dich" badge
- Update specs for new data shapes
