[Docs] Fix DockSight capitalization in the CLI status example

## Location docs/cli.md, docksight status ## Problem The example output says Docksight status: all active, but the product name is consistently written as DockSight elsewhere. ## Correction Change the example output to DockSight status: all active. Check nearby command examples for the same product-name typo, without changing documented behavior. ## Acceptance criteria - The example uses DockSight. - No command behavior is changed. - The issue remains documentation-only.
