fix(nav): drop the redundant "Home" group label from the desktop sidebar

The sidebar has exactly one nav group, and the first entry is already
"Dashboard" pointing to `/`, so the "HOME / Dashboard" pairing used to
read as if there were two separate destinations for the homepage. Drop
the group label and retire the `nav.home` locale key in every bundle.
The collapse toggle keeps its position at the top-right of the strip.
