feat(argocd): let apps override their destination namespace; kadans-jobs → kadans

The destination namespace was hardcoded to the app name. A per-app
`namespace` override lets siblings share one: the kadans-jobs analysis
façade now deploys into the `kadans` namespace alongside the app it
serves, instead of a namespace of its own.

Default is unchanged ($ns defaults to $app_name), so every other app
renders byte-identical.
