Filter workspaces by Researcher name / email

Description

As a TRE Administrator I want to be able to filter workspaces based on the Researcher's user name / email so that I can easily find the correct workspace when responding to help emails that do not provide context for the workspace.
Even better if the results can be sorted to display workspaces in order of time since last action by the Researcher in case the Researcher has been assigned to multiple workspaces. This assumes the most recently accessed VM is the most likely to be the cause of the Researchers issues.

PR 4608 already introduced filtering workspaces.
From a UI perspective, the same search bar accepting user emails would seem like a good fit.

Acceptance criteria

• Workspaces can be filtered by user email / name of VMs within the workspace.
• Optional - When filtering on user email / name, the results can be sorted by most recent activity on a VM within the workspace.

Thank you.

Start by reviewing PR 4608 and the workspace-filtering implementation it introduced. Trace how workspace and VM data reach the UI search bar, then define completion as filtering by researcher name or email; the optional outcome is sorting matches by the most recent VM activity.
