feat(pitch-deck): add passwordless investor auth, audit logs, snapshots & PWA

Implement a complete investor access system for the pitch deck:

- Passwordless magic link auth (jose JWT + nodemailer SMTP)
- Per-investor audit logging (slide views, assumption changes, chat)
- Financial model snapshot persistence (auto-save/restore per investor)
- PWA support (manifest, service worker, offline caching, icons)
- Security safeguards (watermark overlay, rate limiting, anti-scraping
  headers, content protection, single-session enforcement)
- Admin API for invite/revoke/audit-log management
- Integrated into docker-compose.coolify.yml for production deployment
