- auth.js: register chat widget ScriptTag during OAuth callback so every
new install automatically gets the floating chat button — no manual
theme editing required
- server.js: GET /chat/backfill-scripttags endpoint to register the widget
on all already-installed shops in one hit

- Move GET /chat/widget.js before GET /chat/:shop to prevent Express
matching 'widget.js' as the :shop param and returning JSON
- Move POST/GET /chat/:shop after body parser registration so req.body
is populated when customers send messages
