[Client] - Reduce Initial Bundle Size

[Char2sGu]

Desired Changes

Since we have only one AppModule, everything is bundled in the initial bundle, which results in an extreme huge initial bundle:

By introducing lazy loading and module splitting (or perhaps introducing standalone components), the initial bundle size should largely decreased.

PS: In the default build config, the maximum initial bundle size limit is 1mb. However this config is removed in our app.
