feat: complete M0 — legal pages, consent, tip_views metrics, account deletion UI

- /legal/terms and /legal/privacy pages (linked from sign-in)
- Consent (consentGiven=true) recorded on first Google sign-in
- tip_views table: one row per tip served — enables activation + reaction rate queries
- tip_views purged on account deletion
- Delete account button on /connect (confirm → revoke tokens → purge data → sign out)
