Hide /q from dialogs and sort all commands by label

- Add Hidden field to commands.Item for slash-only aliases
- Mark /q as hidden so only /exit and /quit appear in UI
- Filter hidden commands centrally in BuildCommandCategories
- Sort all command categories by label uniformly
- Sort completion items across categories into a single flat list

Fixes #2194
