chore: rename IAM to instance (#11351)

# Which Problems Are Solved

In many cases IAM was used where instance was meant. 

# How the Problems Are Solved

- Rename wrong usage of IAM to instance all over the code base.
- Add an agents.md which explains the terms used in Zitadel's
architecture.

# Additional Context

- closes #11280
