wire user texts routes and update seed

open POST /api/texts and node create endpoints to any
authenticated user; expose new /texts and /texts/{id} pages
plus admin-only GET /api/texts/all. ViewController gains
userTexts and userText methods. seed gives Tanach to the
regular user and adds a second non-admin user.
