[Client] Alt investigation entry points and in-tab navigation

TabModeration gains an Open alt graph button plus alts-table double-click, both routing to the User Alts tab. UserContextMenu gains an Investigate alts action. TabAlts gains row double-click navigation with a Back history stack so moderators can walk the alt graph without retyping names.
