fix(launcher): implement reliable click-outside-to-close for cfg drawer

Flowbite's built-in outsideclose was unreliable for this side-drawer setup.
Root cause: Flowbite's _onclick handler uses dlg.getBoundingClientRect() to
detect backdrop clicks. This works in theory for showModal() dialogs, but
something in the Svelte transition / stacking context prevented it firing.

Fix: bypass Flowbite's detection entirely.
- onclick prop on <Drawer> is spread through Flowbite's restProps chain
  to the native <dialog> element, overriding the broken _onclick handler.
  Handler: just closes the drawer unconditionally.
- A stopPropagation wrapper div around all visual panel content ensures
  that clicks INSIDE the panel never bubble up to the dialog element.
  Only genuine backdrop clicks (outside the visual panel area) reach
  the dialog and trigger the close handler.

ESC key is unaffected — it fires oncancel not onclick.
