feat(componentInstance): add CCRN fields as attributes

[MR2011]

Task Description

Add the following fields to the ComponentInstance model in the database schema, entity and API:

• Region
• Cluster
• Namespace
• Domain
• Project

Expected Test:
Add the new attributes to the existing tests in:

• e2e: component_instance_query_test.go
• app: component_instance_handler_test.go
• db: component_instance_test.go

As discussed, the specified attributes will not be added to ComponentInstanceInput. Instead, they will be extracted from the CCRN line.

Therefore, the ticket scope also includes implementing a parser. This parser must be usable both in end-to-end tests and within the application.
