vmui/logs: improve UI functionality (#6688)

* add a toggle button to the "Group" tab that allows users to expand or collapse all groups at once
* introduce the ability to select a key for grouping logs within the "Group" tab
* display the number of entries within each log group.
* move the Markdown toggle to the general settings panel in the upper left corner.
