style(chat): unify on the bubble-clock icon and rename "All Chats" to "Recents"

The title-bar chat switcher and the home tray launcher pointed at the same
chat history with different icons and names. Both now use the BubbleChatDelay
icon (the switcher's chat-bubble-with-clock), and the launcher (plus the
switcher's tooltip and aria labels) reads "Recents".
