[STORY] As a programme coordinator I want to have a set of maintenance info/options in the show list, to organize the programme with ease

Parent: [EPIC] List all shows view (#160 - closed)

A set of information and operations which is only visible/accessible for the programme coordinator / administrator roles.

Following fields & operations should be available from the show list:

• Display show.internal_note (Compare #152 (closed))
• Display "Last edited by show.updated_by at show.updated_at" for every show list item. Adapt the wording to how it best fits the UX and space. Maybe plain metadata is sufficient.
• Display the button to create a new show, which is currently located in the show list dropdown. It is also suggested to remove it from the dropdown, since it is quite overloaded already.
