fix(soma/menubar): 3 errores de tipo de la infra Menubar.Panel

Reparan el commit anterior (era WIP con errores de svelte-check; runtime OK):
- provider: `tabindex:-1` en los props del panel estaba duplicado (focusScope.props
  ya lo aporta con el mismo valor) → quitado el explícito.
- menubar-panel: el prop `style` (de PrimitiveDivAttributes = `Record<string,unknown>`)
  no encajaba con el opt del provider (`StyleProperties`) → cast en el create.
- test: `props['aria-haspopup']` no es clave estática del tipo (es atributo del morfo
  resuelto por renderProps en runtime) → acceso vía cast a Record.
