Fix ArgoCD secret management - delete with helm uninstall

Change admin password handling so it's properly managed by Helm and gets
deleted when running helm uninstall, while using a fixed password instead
of random generation.

Changes:
- Set fixed argocdServerAdminPassword in values.yaml
- Remove configs.secret.createSecret: false (use Helm default: true)
- Remove argocd-secret.yaml (Helm creates it now)
- Update Justfile to not apply manual secret
- Password: "argocd-admin-default" (bcrypt hash in values.yaml)

Behavior:
- helm install: Creates secret with fixed password
- helm upgrade: Updates secret to fixed password (resets any UI changes)
- helm uninstall: Deletes secret along with all resources
- Secret has Helm annotations (managed by Helm)

This is standard Helm behavior - the password in values.yaml is the
source of truth. User can change via UI, but helm operations will
reset it to the configured value.
