fix(dashboards): Persist global filters when adding widget to dashboard

Apply dashboard global filters to widget query conditions before passing
them to the Add to Dashboard modal. Previously, filters like
span.system or sentry.normalized_description were lost when using
'Add to Dashboard' or 'Open in Widget Builder' from the widget
context menu.
