v4.0.170

Update with one click, and two reverse-proxy / reader fixes.

docker pull ghcr.io/new-usemame/calibre-web-nextgen:v4.0.170
# or :latest

Added

• Update from a button instead of hunting for the right Docker command. When a new version is available, the update banner and the Admin page show an Update now button with the exact one-line command for your setup — Docker Compose, docker run, Unraid, or Portainer/Synology — with one-click copy. A new Automatic updates section under Admin → NextGen Settings walks you through hands-off updates with Watchtower. The README gains a matching "Updating" guide, including Podman. (Admin only.)

Fixed

• The epub reader's Settings panel no longer sits flush against its edges. After the recent settings redesign, the option labels were pressed against the left edge and the slider readouts ("150%", "0px") were clipped on the right. The panel insets its content again and the "Settings" title keeps its full-width bar. Reported by @sambong.
• The Duplicate Books page works again behind a reverse proxy on a sub-path. The cover placeholder kept requesting generic_cover.svg forever, and dismissing or resolving a duplicate group failed with "Failed to update duplicate group" — both from page URLs that dropped the proxy's sub-path prefix. They carry it now. Reported by @chloeroform.

Thanks to @sambong and @chloeroform for the reports.
