Settings was still a top-level navbar item; per feedback it belongs in
the profile dropdown instead, above Sign out. The navbar now only shows
Inventory for everyone.
The navbar previously listed Item Types, Users, and Settings as three
separate top-level links. They now live under a single "Settings" entry
in the navbar, backed by one unified section with a left sub-nav (General,
Item Types, Users) shared across all three areas so it reads as one
settings panel rather than three disconnected admin pages.
- New templates/partials/settings_nav.html shared sub-nav, included by
settings.html, itemtypes_list/form.html, and users_list/form.html.
- Routes moved under /settings/: /item-types* -> /settings/item-types*,
/users* -> /settings/users*. All redirects, form actions, and the
item-type custom-field JS base action updated to match.
