Add a new route that defaults to widget source of path

[elliotBraem]

Add a new route that will default to a page with mob.near/widget/WidgetSource and the :path passed to the child.

Some suggestions for what the route may be:

/w (widget)
/s (source)
/i (inspect)

Current address: https://everything.dev/mob.near/widget/WidgetSource?src=efiz.near/widget/Things.list
Should be: https://everything.dev/i/efiz.near/widget/Things.list
