fix(notifications): a notice value is no plain string, so a translated name cannot freeze in one language

A name goes in as raw(), a translated word as its own msg(): tsc now lists every value, and the
ones that froze are said when shown — Watch later and an untitled channel in the pin and channel
notices, a Plex season's name in its removal toast (a new seasonTitleText, which seasonTitle says).
