Reply All was advertised (keyboard-shortcut label + i18n key) but had no handler. Wire it up: new computeReplyAllRecipients helper puts the sender in To and every other original recipient in Cc, excluding self and de-duping case-insensitively. Adds a button, the `a` shortcut, and a context-menu entry in MessageBrowser, plus a per-message button in ThreadDetailView.
