fix(selectors): prevent unresolved env var templates from leaking into context

- Fall back to undefined instead of raw template string when env var is
  missing from store, so the null-check in the context loop discards it
- Use resolvedDetailId in query cache key so React Query refetches when
  the underlying env var value changes
