The uploaded-blueprint thumbnails on the map settings page and the
setup wizard used the raw setting value (/api/settings/map-blueprint/
...), which resolves at the server root and 404s under a subpath
mount - while the map itself resolves through blueprintUrlFor and
worked. Wrap the previews in withBase.
The monolithic tab page competed with the settings rail as a second
navigation system, and its Integrations tab was a dumping ground. Each
section is now its own routed rail page (ServiceNow, Zabbix Supplies,
Dell Warranty, Collector PC Types, Branding, Floor Map, Printing and
Labels, Email/SMTP, Audit, Authentication, Asset Identifiers, Global
Search), thin over a shared useSystemSettings composable, grouped
logically in the rail with system groups clustered last. Old
/settings/system?tab= URLs redirect to the right page.
Also fixes the post-login redirect: the auth guard now remembers the
intended destination and Login returns there (same-site paths only).
