Build GDPR compliance system: data export, account deletion, consent

- Data export (Art. 15/20): GET /api/gdpr/export serves a full JSON export
  of the user's data (credentials/tokens excluded, exclusions declared)
- Right to erasure (Art. 17): self-service deletion with 30-day grace
  period (Settings -> Privacy & Data), cancellable; daily /api/cron/gdpr
  drain cancels Stripe billing, purges Spaces files, cascade-deletes the
  account, anonymizes consent rows, and writes audit evidence
- Migration 0011: account_deletion_requests (partial unique index = one
  pending per user) + FK-less consent_log (survives erasure)
- Consent: terms/privacy acceptance logged at signup (email + Google);
  cookie banner with analytics opt-out (umami.disabled), choices logged
  server-side for signed-in users via POST /api/gdpr/consent
- Admin deleteUser upgraded to the same full purge (was leaving Spaces
  files and Stripe subscriptions orphaned)
- /gdpr legal page now points at the self-service tools
- scripts/verify-gdpr.ts: end-to-end verification vs live dev DB (22/22)
