Fix Updates tab compile + CI failure propagation

- settingsdialogupdates.cpp missed an include of settings.h (it was only
  getting the forward-declared version from settingsdialog.h), which
  broke every settings().setX() call. Now included directly.
- UpdatesSettingsTab is not a QObject so it has no tr() member; add
  Q_DECLARE_TR_FUNCTIONS to get a static tr() via QCoreApplication.
- CI: the docker run chained commands with `;` so a ninja failure got
  masked by the trailing `ccache -s`. Capture the build-inner.sh exit
  status and `exit $status` at the end so real build failures fail the
  step instead of bleeding into the tar packaging step and producing a
  confusing "Cannot stat: No such file" error.
