Add platform settings (Stage 9)

- Settings key-value table in Prisma with migration - getSettings() / getSetting() helpers in lib/settings.ts - Admin UI at /admin/settings with 6 sections: General, Notifications, Student profile, Legal docs, Curator permissions, Code injection - saveSettings() server action with admin-only guard - Maintenance mode: non-admin users redirected to /maintenance page - schoolName propagated to page metadata and all email templates - headCode / bodyCode injected into root layout <head> and <body> Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
