* feat: Add `uc ps` command to list all containers in the cluster
* Fix indentation
* Improvements to the container state highlights code (use enum, better var naming)
* Add group/sort option by "health"
* Rename `uc ps --group-by` flag to `--sort`. Also, remove `--context` flag.
* Use huh.spinner with standard style/type
* Remove pointless TrimPrefix on container name
* Move machine lookup out of services loop
* Use more efficient `ListServiceContainers`
* Use consistent header other
* Use api.ProxyMachinesContext helper for context to query all machines for service containers
* Make errored MachineServiceContainer entries a warning, not return an error immediately, in `uc ps`
* Use lipgloss table instead of tabwriter for "uc ps" command
* Handle nil metadata in `uc ps` on container when cluster only has one machine
