[Cases] All cases table: bulk actions & single actions

[cnasikas]

From the all-cases page, users can filter and view their cases. Only bulk deletion is supported at the moment. We should add the following bulk actions:

• Change status
• Edit tags
• Edit assignees
• Change severity

The same actions should be added to the actions column. Users should be able to perform the same actions on each case individually.

Tasks

• Convert delete and update cases hooks to use react query ([Cases] Convert delete and update cases hook to react query #141920)
