- Remove "6." / "7." prefixes from Tools and Settings nav labels and page titles
- Add a horizontal separator (nav-sep) before the Tools/Settings group
- Move Tasks into the nav as a regular nav-item after the separator,
replacing the separate tasks-nav-btn at the sidebar bottom
- Tasks item retains the active-count badge (tasks-nav-count)
