Implement multi-user RBAC: database, auth, routing, admin API (Phases 1-6)
Phase 1: Add role, mfa_enforce_pending, must_change_password to users table.
Create system_config (singleton) and audit_log tables. Migration 026.
Phase 2: Add user_id FK to all 8 data tables (todos, reminders, projects,
calendars, people, locations, event_templates, ntfy_sent) with 4-step
nullable→backfill→FK→NOT NULL pattern. Migrations 027-034.
Phase 3: Harden auth schemas (extra="forbid" on RegisterRequest), add
MFA enforcement token serializer with distinct salt, rewrite auth router
with require_role() factory and registration endpoint.
Phase 4: Scope all 12 routers by user_id, fix dependency type bugs,
bound weather cache (SEC-15), multi-user ntfy dispatch.
Phase 5: Create admin router (14 endpoints), admin schemas, audit
service, rate limiting in nginx. SEC-08 CSRF via X-Requested-With.
Phase 6: Update frontend types, useAuth hook (role/isAdmin/register),
App.tsx (AdminRoute guard), Sidebar (admin link), api.ts (XHR header).
Security findings addressed: SEC-01, SEC-02, SEC-03, SEC-04, SEC-05,
SEC-06, SEC-07, SEC-08, SEC-12, SEC-13, SEC-15.
