🐛 Error logging in when a users namespace has been removed

[michaeljcollinsuk]

Describe the bug.

User reported an error when logging in via support https://github.com/ministryofjustice/data-platform-support/issues/411

Corresponding sentry error showed a 403 trying to access the user namespace https://ministryofjustice.sentry.io/issues/4155701134/?environment=prod&project=5606313&query=is%3Aunresolved&referrer=issue-stream&statsPeriod=14d&stream_index=2

On investigation the users namespace did not exist. This was causing an exception when trying to look up existing deployments when visiting the "My tools" page, this is not caught, so the user sees a 500 error.

To Reproduce

N/A user specific

Expected Behaviour

1. We should catch the exception in the view, to avoid the user seeing a 500 error
2. In the backend, recreate the namespace and inform the user this is ongoing and will take a few minutes
3. Send event to frontend when the namespace has been created (use django channels)
