Deleting a workspace deletes its sessions

What changed

Deleting a workspace from the agent session workspace view now deletes the workspace row and all sessions under that workspace. The actual folder on disk is not deleted.

Why this matters to the user

Users who delete a workspace group from the sessions list will also remove the sessions shown under that workspace group, instead of only detaching those sessions from the workspace.

What the user should do

Nothing automatic is required. Before confirming a workspace delete, make sure the sessions under that workspace are no longer needed.

Notes for release manager

The confirmation dialog in the app explains that only database records are removed and the real folder remains on disk.
