ns8 modules: always generate the module logo image instead of inlining it as base64

[andre8244]

Description

NS8 module UIs ship their logo as ui/src/assets/module_default_logo.png. With the default
url-loader limit, webpack inlines images below the threshold as base64 data: URIs, so the
logo file is not always emitted as a real file in the build output.

The fix is a single block in the module ui/vue.config.js, which disables base64 encoding for
images:

chainWebpack: (config) => {
  config.module
    .rule("images")
    .use("url-loader")
    .loader("url-loader")
    .tap((options) => {
      // Do not base64 encode images URLs. Needed to always generate module logo image
      options.limit = -1;
      return options;
    });
},

It has already been added ad hoc to about half of the modules. This task is to apply it to the
remaining ones, so every module behaves consistently.
