Networks#show: Move header links into a decorator

In order to allow us to use these links in tables of networks via the
new table builder, move the link definitions into decorator
`#action_links`.

This changes both of these types of pages:

* http://stif-boiv.dev:3000/referentials/4/networks/118
* http://stif-boiv.dev:3000/line_referentials/1/networks/118
