Deploy companion to KCP dev

[Teneroy]

We need to deploy companion to KCP dev for our frontend team to have endpoints to reach. Let's deploy it manually for the scope of this task. You can use existing instance for HanaDB or create a new one.

Acceptance criteria:

• Companion is deployed to KCP dev
• Deploy Redis and Langfuse to KCP dev
• Create new instance for AI-Core
• The deployment way and the way to reach endpoints is documented
• Write down a small guide on how to update a companion whenever we introduce new features important for busola team

Comment: maybe you can use deployment YAML that we use in our GitHub pipelines
