ShellPage's JSX carried the whole sidebar inline, including two near-copies
of the group header and of the main header's sidebar toggles, which made the
render hard to follow and easy to change in one place only.
Move-only: the sidebar header, group header (one component for the
conversation and project variants), the team and project roster rows, the
archived section, the user menu and the sidebar toggle buttons now live in
pages/shell. DOM, classNames, test ids, aria attributes, handlers and messages
are unchanged; the catalogs only update their file references, and the
desktop source checks for the header toggles now read the file they moved to.
