[REM] Removed disabled_db=True from ir_http's auth="none"

[MOV] ensure_db() helper from http module to web module

Since we removed auth="admin" in favor of auth="none" with explicit superuser id usage,
the disable_db clause in auth_none() has only sense for the /web and /web/login routes.
The web module is an exception because it's routes are registered for the nodb dispatching.
This is why the ensure_db() helper is moved to web client and will take care of the
web's auth="none" routes that needs a db to work with
