feat: Add complete PDPA compliance pages

- Admin dashboard (/admin/consent-logs) with password auth
- Consent API (/api/consent) with SQLite + IP hashing
- Privacy Policy (Thai) - PDPA Section 36 compliant
- Terms & Conditions (Thai) - 9 standard clauses
- .env.example template with Umami placeholder

All pages preserve current design system.
