Rapidly switching filter chips, sort columns, or pagination on the devices
and notifications lists could overlap fetches, and an older response
landing after a newer one would silently overwrite the list with results
that no longer match the active query.
Thread an optional CancelToken into listDevices and listNotifications.
Each State now keeps one active token, cancels it on every new fetch and
on dispose, and bails from both success and catch branches when its token
has been superseded. DioExceptionType.cancel is silenced so internal
cancellations don't surface as user-visible errors. The notifications
list's prior `if (_isLoading) return;` guard is removed so the 1-min
periodic refresh is no longer skipped during user activity.

Set 5s/15s/15s connect/receive/send timeouts so calls fail fast instead of
hanging. Introduce dioErrorToUserMessage() and route DioException-throwing
call sites (device actions, devices list, notifications list, scanners
status card) through it, replacing raw e.toString() output. Notifications
list now surfaces load errors inline in the theme's error color, matching
the devices list pattern. Status dots show the mapped detail as a tooltip.
Stop logging the API key in cleartext.

Subscribes the devices list and notifications list to a shared
RouteObserver so they refetch when a pushed route (e.g. device detail)
is popped, avoiding stale state after registering or updating a device.

Mirror the notifications list paging pattern (offset/limit, fetch one
extra row to detect the next page, First/Prev/Next controls) across the
devices DB query, REST endpoint, API client and UI. Also add a First
page button to the notifications pagination row.

HomeScreen is now a StatelessWidget responsible only for the responsive
layout structure. All notification state, pagination, filtering, and
mark-as-read logic lives in the new NotificationsList widget.
