docs(extensions): fix logic errors and code-doc drift in chatbot SIP

- Fix broken getCurrentDashboard example (syntax error, raw nativeFilters/
  slices exposure contradicting the "normalized only" point, wrong field
  names, missing ChartSummary.isVisible)
- Correct page-type vocabulary: `chart` -> `explore` to match PageType
- Stop claiming `icon` is "proposed" — it already exists on the View
  descriptor and the registration example already passes it
- Remove phantom "UI-control state" and navigation "focused entity"
  promises that no contract actually exposes
- Distinguish implemented namespaces (dashboard/explore/navigation) from
  specified-but-not-implemented ones (dataset, DashboardContext.charts)
- Fix malformed `explore` status marker; align getViews descriptor field
  list to include `icon`
