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 is mostly a direct application of the ember-angle-brackets-codemod.
I manually restored newlines in multi-line component invocations, usually
preserving file line length except for now-non-positional link-to @route.
I needed to rename task to taskState in some cases to avoid Ember
Concurrency naming conflicts.
Now that job summary is pushed into the store from the list request
and the task group count is derived from the summary, the detailed
job information is no longer needed for a job row.
