feat: add hint section to MCP overview page

[Lasserich]

What this PR does / why we need it:

The current MCP page seems a bit empty with no clear guidance on what is going strong or wrong. This feature adds so called hints which are stats on your MCP, including overall managed resource health, GitOps state and soon to be external-secrets state.

Further

•  Make only one getAllManagedResources call instead of having one call in the table, graph & hints
•  Currently language is not properly implemented
• Currently the external secret does not display any stat yet
• Make stats more sophisticated (e.g. How many resources are healthy/creating etc.?)

Do you know the issue with forbidden package origin from the pipeline? @lucasgoral @Hubert-Szczepanski-SAP

Have you tried to adjust the zIndex to lower one?

[Lasserich]

did play around a little but I do also like the current approach of it taking space instead of layering over the chart. Is this also fine for you?

We should't have an button that is blue (active) but has no action assigned. Maybe you can disable it?

I think you are still on an old branch, please take a look at the PR header. Is this more what you envisioned? Goal from my side is to nudge the user to take a look at why this component is disabled, and then get to our docs explaining the benefits of this component and how to enable it. WDYT?
