[OC 16.1] Infinite loop of printing warning message when trying to add recording

[scharnkn]

Describe the bug

During event creation, the web client/Admin UI creates an infinite loop when warning the user about not being able to change access rules due to another episode processing in the same series.
As a result event creation cannot be finished while the other event is still processing. In addition, the browser will have a spike in CPU usage until the event creation dialog is closed.

To Reproduce

This behaviour can be reproduced on stable.opencast.org:

1. Create a new series names "Test Series"
2. Upload a new event "Test Event 1" into this series and let the processing start
3. Now while "Test Event 1" is still processing, create another event in "Test Series"
4. Proceed in the event creation dialog up until the "Access policy" tab, where the warning should now be spammed indefinitely

Expected behavior

The warning should only be shown once.

Screenshots

User environment:

• Device: PC
• OS: Debian 12
• Browser Chrome
• Version 126.0.6478.126

Additional context

This behaviour was observed with the new Admin UI, I haven't tested whether this also happens with the old Admin UI.

Moving this to the admin interface repository since it seem to mainly be a UI problem.
