Apply CORS restrictions

[turnerrainer]

AS InfoSec
I WANT CORS restrictions to be applied
SO THAT potential attack surface would be smaller

Acceptance Criteria

• Set Access-Control-Allow-Origin header to define which origins are allowed to access the resource
• Set Access-Control-Allow-Methods header to define the HTTP methods (GET, POST, PUT, etc.) that are allowed for cross-origin requests

Scope

• Public Ruuter
• Private Ruuter
• TIM
• Chat Widget
• Backoffice

Changed the ingresses, so that some values that were hardcoded, will use values.yaml as a source
Went over the components/modules in scope to check that the CORS values are set
