v0.1.0-alpha.9

• PfDrawer: SSR-safe use of document and window (scroll lock, scale wrapper query, global listeners, deferred setTimeout) so server renders (e.g. Nuxt) do not throw ReferenceError or return HTTP 500 when watchers run without a DOM.
• PfDashboardSidebarCollapse: toggling no longer calls toggleCollapsed() (which was a no-op unless PfDashboardSidebar had collapsible); it now calls setCollapsed() so the control works with default sidebar props. Default icon-only styling (iconOnly, aria-label) for a square, centered icon button.
