feat(status-bar): improve status bar display and actions

[skyrpex]

• The status bar will always show the LS instance status (running, stopping, etc) if the LS CLI is installed — it doesn’t need to have the full setup complete
• The status bar commands will always allow starting and stopping LS if the LS CLI is installed — it doesn’t need to have the full setup complete
• The status bar setup wizard command will be displayed on top of the rest of the commands
• The status bar will be red if any part of the setup is incomplete
• The status bar text now uses a colon as a separator, instead of parentheses

Great improvement, thank you! Commands are much more relevant to each situation now. And the code is much more straightforward thanks to the introduction should... functions. 👏
