non-reconciliable & readiness of static objects

Remove reconcile subcommand for static object APIs Alerts and Providers.

Add a isStatic() method on all the object adapters to determine if
they are static and don't have reconciler. The objects that don't
have reconcilers are skipped from reconciliation and readiness
checks like HelmRepository of type OCI.

Add default ready message for `get` subcommand output for static
objects, Alerts, Providers and HelmRepositories of type OCI, as ready
message can't be derived for them from their status.
