Add a link to the internal collection in workflow and work requests

When trying to debug workflows, it's quite useful to be able to browse the internal collection associated to a workflow. We hide those collections from the list of collections because they are noise and internal details, but it should still be possible to find them out somewhere.

I propose to add them as a link in the right panel of a work-request/workflow view. There's a bootstrap icon for a collection: https://icons.getbootstrap.com/icons/collection/ Or a table: https://icons.getbootstrap.com/icons/table/ Or a database: https://icons.getbootstrap.com/icons/database/ Or a backpack: https://icons.getbootstrap.com/icons/backpack/ (it's stuff that we carry with the workflow?)
