Decidim: Link in admin to pre/view item in the front end, and viceversa

[furilo]

Part of #3343

Proposal

To the admin:

To the front:

Or something lighter:

We have other items that are lists (proposals, debates...); some of them already have the view icon, in others we would just have to add it.

Simpler alternative (suggested by @andreslucena) - just a "View" link in the header:

Hi! I just saw this and have a question. I think I "fixed" this in the past by converting the title in a link to the frontend when it makes sense. Is this known but we're looking for a more explicit solution?

[mrcasals]

Yup, this is known @deivid-rodriguez, but @decidim/product wanted a more explicit solution, as you say 😄

Also note that this issue asks to add links from the public part to the admin too! (we don't have those by now)
