Implement full consent logging system with SQLite database

- Install better-sqlite3 and @astrojs/node adapter
- Update consent API to use SQLite database
- Add DELETE endpoint for consent logs
- Update admin consent-logs page with full UI (stats, table, export, delete)
- Add sessionId to consent tracking
- Admin password: Coolm@n1234mo

Note: Database stored at data/consent.db (gitignored)
