ci(windows-smoke): tray, badge, taskbar, thumbbar and media-control commands (#4, #7)

Call each with what cinny sends (badge, unread, call state, thumbbar,
SMTC, taskbar progress, jump list, update-ready, flash), then reset;
every call must succeed and the app must still respond.

Refs #4, #7, #19
