[Client] Settings: open Settings as a tab

Add a singleton TabSettings hosting the shared SettingsView and retarget
the menu action, tray entry, shortcut and room chat deep-link to
TabSupervisor::openTabSettings. Close validation moves from
DlgSettings::closeEvent to TabSettings::closeRequest with tr() contexts
preserved as DlgSettings. The modal stays but is no longer referenced.
