Description

Tested on E2E in Firefox:
When creating notifications on tombstones, Trace-X stops working for me.
Additionally, it's not possible to send notifications with tombstones, but the error message is unclear.

Current behaviour

I can create a notification for tombstones, but when trying to type in a description, the application stops working and firefox reports that the page is slowing down the browser.

Also, no BPN is selected and the field can't be edited, so there's no point in creating this notification as it may never be sent anywhere.

There's still the possibility that notifications for tombstones exist, as parts may be replaced by tombstones after synchronization. It's not possible to approve and send those notifications anymore, but it can be approved anyways. When doing that no error message is created and the error pop-up is not descriptive:

Expected behavior

• It may not be possible to create notifications on tombstones.
• The "Create notification" action must be greyed out with a tooltip "It is not possible to create a quality notification for tombstones." / "Die Erstellung eines Qualitätsthemas für Grabsteine ist nicht möglich", when a tombstone is selected.
• Tombstones may not be seen or selected in the create notification screen.
• If a notification has a tombstone because of synchronization issues or for any other reason, the 'Approve' action is greyed out and not possible for that notification with a descriptive tooltip (e.g. "Notification can't be approved for tombstones. Please synchronize this part or select a different one.")

Steps to reproduce the Bug

Scenario 1: Creating notifications for tombstones

1. Log in as supervisor in Trace-X A
2. Select a tombstone
3. Create a notification for it
4. Application crashes

Scenario 2: Sending notifications with tombstones

1. Log in as supervisor in Trace-X A
2. Select any supplier part (not a tombstone)
3. Create an investigation for it
4. Log in as administrator in Trace-X A
5. Create a valid policy with the BPN of Trace-X A with constraints different to the default-policy
6. Select the supplier part from step 2
7. Trigger the part synchronization for it -> It should now be a tombstone
8. Log in as supervisor in Trace-X A
9. Go to the investigation created in part 3 -> It should only have the tombstone
10. Approve the notification -> It can't be sent

DISCUSSION_NEEDED:

• Should users be able to create notifications for tombstones?
• Should it be possible to send notifications with tombstones? -> If not, how should we handle that situation?

EDIT: Decision taken from #874 -> Notifications may not be created for tombstones & Notifications with tombstones may not be approved by disabling the 'Approve' action.
