This rethinks namespaces as a filter on list pages rather than a global setting.
The biggest net-new feature here is being able to select All (*) to list all jobs
or CSI volumes across namespaces.
This continues iteration on the DAS UI by adding the ability to directly
navigate to a recommendation summary by (namespaced) slug and a copy
button for the direct navigation link.
It includes a change to CopyButton allowing it to take a block that’s
rendered within the button.
It also changes some instances of multi-relationship traversal to use
in-summary attributes, such as summary.jobNamespace instead of
summary.job.namespace.name.
