feat(web): add copyright notice + footer/toolbar polish (#1639)

- Add a grey CopyrightBadge ("Copyright © Model Context Protocol a Series of LF
  Projects, LLC.") to the footer. Version (bottom-left) and copyright
  (bottom-right) share the bottom `xl` margin band: vertically centered in it
  and inset by `xl` to line up with the content's left/right margins.
- Move the list expand/collapse toggle to the right of the "Add Servers" button
  in ServerListControls.
- Make the monitoring column's close-sidebar control match the open-sidebar
  PinColumnButton theme (Button size sm / variant subtle) instead of a gray
  ActionIcon, so the open/close affordances read as a pair.
