kctrl: UX enhancements

[100mik]

Describe the problem/challenge you have
A bunch of snacky tweaks that will enhance UX. These might be resolved across multiple PRs.

Describe the solution you'd like
Listing AIs in the acceptance criteria

Anything else you would like to add:

• When a reconciliation completes we should be logging Deploy complete instead of `App reconciled to stay consistent with the other stages
• Colour app list status column
• Colour package installed list status output column
• Conditions in get shouldnt include reason/message when empty (check for missing omitempty tags) (Relevant PR Switch YAML library used to sigs.k8s.io/yaml cppforlife/go-cli-ui#11)
• Handle invalid package names better (example: kctrl pkg i -i contour -p foo)
• Explore if we need to leverage wordwrapping for certain columns in list and get commands. This can diverge into a separate issue if it warrants it.

Adding a few more to the list:

• Add shorthand -v for --version in package installed command.
• Add namespace name to not found errors.
• Update package installed list example to use -A instead of A.
• Update error message to be more user friendly when values and values-file-output flag are used for a package install with no values.yml
• Update error message for package available get -p <pkg-name> --values-schema to include information about how to specify a version
