## Summary
In some SI cases, handling of the accounts happens in a different flow. In those cases the investigation is not needed anymore and simply needs to be closed. To remove this manual work we should close these cases automatically to remove noise and unnecessary clicks.
## User story
As a checkuser:
- I do not want to see open cases that already have all the accounts blocked and do not require any action
- I want to know the historical information that this case existed and was closed automatically by the system
- I want to be given time for this automatic case closing to apply so that I can close the case with a relevant note after processing the case
## Acceptance criteria
- [ ] Automatically close cases when all the accounts are already blocked
- [ ] Append a note 'Automatically closed as all accounts blocked'
