fix: restore org-only usage hint format and use explicit org/project in tip

- Revert ContextError usage hint to `sentry event view ${org}/ ${eventId}`
  (the space after the trailing slash is intentional — it represents
  <org>/<no_project> <event_id> format)
- Change stderr tip from env var guidance to the explicit command form:
  `Use: sentry event view ${org}/${project} ${eventId}`
