feat: enable toggle workspace, invalidate on workspace update

[alex-mcgovern]

• adds a "mutation" hook to the workspace selection component, which allows toggling workspaces
• wraps the app a custom react-query QueryClientProvider, which subscribes to events in the query cache to enable the following
  • when the cached value for GET /api/v1/workspaces/active is updated, the provider will compare the active workspace ID — if it is new, it will invalidate the query cache and post a toast notification with the newly activated workspace name
• a useActiveWorkspaces hook is implemented, which polls the server on an interval, as well as every time the window is focused, or it reconnects — this should ensure that it is always up to date
