fix: improve cloud CLI status and error messages

- Simplify `bm cloud status` output: remove verbose health check details
  (status/version/timestamp), show simple "Cloud connected" / "Cloud not
  connected" message instead
- Improve `bm reindex --project` error for cloud projects: distinguish
  between "project not found" and "project is cloud-only" with a helpful
  message explaining reindexing is a local operation
- Improve `bm project list` cloud error message: show the actual error
  and soften the credentials suggestion
- Add tests for cloud status command (5 tests)
