- Add centralized Zod schemas (server/utils/schemas.js) and validateBody

updates, verify-payment, and admin event creation endpoints
- Fix logout cookie flags to match login (httpOnly: true, secure
conditional on NODE_ENV)
- Delete unauthenticated test/debug endpoints (test-connection,
test-subscription, test-bot)
- Remove sensitive console.log statements from Helcim and member
endpoints
- Remove unused bcryptjs dependency
- Add 10MB file size limit on image uploads
- Use runtime config for JWT secret across all endpoints
- Add 38 validation tests (117 total, all passing)
Auth: Add requireAuth/requireAdmin guards with JWT cookie verification,
member status checks (suspended/cancelled = 403), and admin role
enforcement. Apply to all admin, upload, and payment endpoints. Add
role field to Member model.
CSRF: Double-submit cookie middleware with client plugin. Exempt
webhook and magic-link verify routes.
Headers: X-Content-Type-Options, X-Frame-Options, X-XSS-Protection,
Referrer-Policy, Permissions-Policy on all responses. HSTS and CSP
(Helcim/Cloudinary/Plausible sources) in production only.
Rate limiting: Auth 5/5min, payment 10/min, upload 10/min, general
100/min via rate-limiter-flexible, keyed by client IP.
XSS: DOMPurify sanitization on marked() output with tag/attr
allowlists. escapeHtml() utility for email template interpolation.
Anti-enumeration: Login returns identical response for existing and
non-existing emails. Remove 404 handling from login UI components.
Mass assignment: Remove helcimCustomerId from profile allowedFields.
Session: 7-day token expiry, refresh endpoint, httpOnly+secure cookies.
Environment: Validate required secrets on startup via server plugin.
Remove JWT_SECRET hardcoded fallback.
