DX: Improve Bundling

[slayb3ar]

Two main issues with our bundling approach

1. Requires webpack / node / NPM
2. Bundle size is huge (.5 MB)

We need to address 1 and/or 2 via webpack configuration (or a different bundler altogether) or usage of import maps

Import Maps: Advent of import maps allows for us to migrate from webpack. https://github.com/dropseed/django-importmap.
