fix(api): remove CSRF middleware that breaks POST/PUT/PATCH/DELETE

The CSRF middleware requires x-csrf-token header but the frontend never
sends it, which would break all mutating operations with 403 errors.

CSRF protection should be implemented in a separate coordinated PR with
frontend changes.
