App Store rejection: missing privacy policy link on sign-in screen

## App Store Rejection — Review ID: 2024-ARB-88812

### Screenshot
[See Figma: iOS Auth Screen v1.2 — missing footer links]

### Fix Required
Add Privacy Policy and Terms of Service links to:
1. Sign-in screen footer
2. Settings > Legal section
3. App Store listing description

### Status of Privacy Policy
- Privacy Policy: Drafted, hosted at vctrl.dev/legal/privacy — LIVE
- Terms of Service: Drafted, hosted at vctrl.dev/legal/terms — LIVE

### Implementation
- Add footer component to AuthScreen with links to both docs
- Links must be tappable, not just decorative text
- Policy must cover: data collected, third parties, user rights

### Timeline

### Lesson
Always add legal links to auth screens before submission. Add this to pre-submission checklist.
