Sort arrstack role apps alphabetically (#133)

The master apply (pipeline 202) fails with "Provider produced inconsistent result after apply": the arrstack Vault engine returns apps alphabetically sorted while the provider models apps as an ordered List, so the declared order [sonarr, radarr, prowlarr] never matches the read-back. This is an interim unblock while the provider moves apps to a Set.

- Reorders apps in config/arrstack_secret_backend_role/arrstack/all.yaml to alphabetical order to match the engine read-back
