Page routes, Home link, documented-app filters, Overview colors and list fixes

- Every nav page has its own address (/tracked, /status, /devices, ...);
  the logo and name go to the Overview; back/forward work.
- List filters gain an "Only ticked" mode; software columns get a one-click
  "devices with only documented apps" pick and an easiest-first sort.
- Overview: the device list uses the dashboard's table header (sticky, with
  Excel filters); what opened it is clearly highlighted; locations colored by
  how much is done (red to green); stages read red / amber / green.
- Details: one-line title bar; presence and monitors only in Advanced View.
- Presence sweep pings only completed pairs (everything else is pinged by
  the sweep itself), hourly and at midnight.
- Custom View scrollbar smaller, in the table header blue.
- Docs: no sideways scroll in the article list; no blank lines around code.
