Was hardcoded to webapp/demo-go-app — any future app added to this
project needed its own policy line. Wildcarding to webapp/* means any
app onboarded into that project (project: webapp in its Application
manifest) is automatically covered, no RBAC change needed per app.
Platform-level apps on the default project are unaffected.
demo-go-app moved from ArgoCD's default project to the new webapp
project (devops-argo-config#7de2f8b). ArgoCD RBAC is keyed
<project>/<app-name>, so the jenkins-ci sync/get policy has to move
with it or syncArgoApp's scoped token starts getting silent 403s on
its next sync.
Adds accounts.jenkins-ci (apiKey) and a repo-scoped RBAC policy
(sync/get on default/demo-go-app only) so devops-lib's syncArgoApp
stage can trigger syncs without full admin access.
