Display all permissions in item permission panel

[smadbe]

Overview

Current the item permission panel (displayed on top of items when observing) only shows "can view" permission. Let's try to display more.

Acceptance criteria

• [ ] If the item is an explicit-entry activity:
  • [ ] if the group has can-view >= content: "At any time (if the activity allows it)"
  • [ ] otherwise "From 20/10/2024 15:21:11 until 20/10/2024 15:21:11 (UTC+2)"
• [ ] Otherwise, don't add anything related to "enter"
• [ ] If the group has can view >= info: add the "Can grant view" permissions (in the same way as the can view perms)
• [ ] If the group has can view >= content:
  • [ ] add the "Can watch" permissions (in the same way as the can view perms)
  • [ ] add the "Can edit" permissions (in the same way as the can view perms)
• [ ] If the group (the observed one, not the current user!) is owner of the content:
  • [ ] add "Is owner" with "true" as value
  • [ ] don't display any of the other permissions !
