Add a dedicated invitation screen
We need a detailed screen for a group.
Create a component under pages/shared/users/group_edit.vue
This page holds an edit field for the group title.
Other than that there is a simple list of users who belong to this group.
The list has: Name, invitation status, remove button
Invitation Status: this is either the invite URL https://url.motionbank.org/Dh23DJa7
or just the notice accepted
or rejected
This URL can be sent to invite others to the group. Please create a copy & paste field (with a button to copy it like they do everywhere now).
You can create a new invitation, and when you do, there is a new line in the list without name (not known yet) and just the URL for you to send as an email. This probably needs a small text explaining what's going on there.
