ROX-33400: vendor ArgoCD v1alpha1.Application

[kovayur]

Description

Currently, to use ArgoCD types, we import the entire ArgoCD dependency, which brings many transitive dependencies into our project. This can lead to dependency update issues (see #2592, #2578) and may require us to use specific compatible versions of other dependencies (e.g. k8s client libs) and our Go runtime. This PR addresses this by "vendoring" the v1alpha1.Application type from ArgoCD. This is a temporary measure until these types are moved to a separate, thin module.

Checklist (Definition of Done)

• Unit and integration tests added
• Added test description under Test manual
• Documentation added if necessary (i.e. changes to dev setup, test execution, ...)
• CI and all relevant tests are passing
• Add the ticket number to the PR title if available, i.e. ROX-12345: ...
• Discussed security and business related topics privately. Will move any security and business related topics that arise to private communication channel.
• Add secret to app-interface Vault or Secrets Manager if necessary
• RDS changes were e2e tested manually
• Check AWS limits are reasonable for changes provisioning new resources
