Make Koja native deps optional to unblock web Docker build

Move Capacitor and cordova-plugin-pushe to optionalDependencies. They are
only needed for the native mobile shell, are never imported by the Next.js
source, and are not served by the Liara npm mirror — so installing them as
hard dependencies broke the web image build. As optional deps, npm skips
them when the mirror can't resolve them.
