fix(bar): resolve 'Show workspace numbers only when occupied' setting

- Fix workspace number container visibility logic to properly reference container.hasWindows
- The 'hasWindows' property was not in scope for workspaceNumberContainer
- Workspace numbers now correctly hide when workspace has no windows and setting is enabled
- Fixes toggle functionality for 'show-numbers-only-when-occupied' setting
