feat: Add command to show aggregate health data

[catmo-syntasso]

As a Kratix user in a less mature org (i.e. no big observability thing)
I want a command to aggregate health data in my CLI
so that I can quickly see if my resources are healthy or not

---

Feedback we got from our health checks testing was:

• Expect people to add things into a dashboard, collector on prometheus.
• Lower maturity teams need a chain of commands, and surfacing information. Dashboards?
• Want: Aggregation of healthiness of fleet, being easily able to check the output of the health record, association of resources within a team

---

Given I have resources with health checks
When I run a kratix get health command (or something that actually fits the format I can't find in notion)
Then I see aggregated information of the status
And if any are unhealthy I see their name so I can find why they are unhealthy.
