[QA] Create space from selection requires uninterupted browser connection

[jnweiger]

Describe the bug

oc-7.0.0-rc.0 started at hetzner cloud via docker compose according to https://docs.opencloud.eu/docs/admin/getting-started/container/docker-compose/docker-compose-base/
Browser: Firefox 140.9.0esr openSUSE 15.6

Log in to the Web UI, Upload a folder with 600 small text files.
Click on the three dots of the folder, choose "Create space from selection"

This process takes long.
After a few minutes, the network goes away (e.g. reproduced by setting the laptop into Airplane mode).
Ca 1h later, there is a message in the browser "Creating Space failed"

The new space is there, but contains only 314 files are present. BAD.

Similar behaviour, when the user closes the browser tab. A message about unsaved information appears. This does not give a hint about interrupting a space creation.

This time I was quicker, the space was created with only 96 Files.

In any case, users visiting the space cannot tell that it is incomplete.

Expected behaviour

• creating a space should be a server side operation, no browser needed.
• When creating a space fails, the space should not exist at all.
