0.3.38: brand-green scrollbars everywhere + captureTab widens the viewport when sidebar shrinks the tab

Browse source 
Two changes shipped together (main.js touched by both this session and a
parallel session in different regions):

Scrollbars — from the "empty white space should be grey, thumb should
be Bitcoin Cash green" ask:
  * new SCROLLBAR_CSS constant + styleScrollbars(wc) helper injects the
    theme on every dom-ready
  * thumb #0AC18E (BCH primary), track rgba(120,130,150,0.18) subtle
    neutral grey so it works on both dark and light surfaces without
    hardcoding either; 6px radius, 2px inset via background-clip:padding-box
  * modern scrollbar-color on <html> for Chromium 121+; ::-webkit- rules
    with !important as the fallback / override for sites that theme
    their own scrollbars — scrollbar-width intentionally left alone so
    a page that hides scrollbars entirely keeps that behaviour
  * hooked into every wc we own: createTab, chrome, popover, enginePicker,
    downloadsPop, addressPicker, pwFillPop, linkStatus, sidebar (so every
    add-on panel like Aegis picks it up), approvalPop
  * fires once immediately if the wc is already past dom-ready when we
    attach — fixed views load fast during startup, we'd otherwise miss

captureTab full-page — from the parallel session's screenshot work:
  * before Page.captureScreenshot with captureBeyondViewport we now
    override Emulation.setDeviceMetricsOverride to the window's full
    content width so an open sidebar (or other on-screen chrome that
    narrowed the tab view) doesn't clip the shot — capture comes back at
    the page's natural full width, not the visible width
  * attach the debugger for the call if it isn't attached, detach on
    return; clear the metrics override in finally so the tab returns to
    its normal layout regardless of success
