ui: resolve list.js dependency for Db Console bazel build

Currently, to manage proper JS dependency resolution with bazel,
we need to do one more extra step (which isn't automated yet):
explicitly specify the list of dependencies required by Db Console
in its BUILD.bazel file.

Another issue that is solved with this change is path resolution for
"node_modules" in Webpack config file. Path resolution for NPM modules
in webpack relies on project structure and it doesn't work well with
the way bazel places outputs.

Release note: None
