lebaudantoine 07a1425fee ️(frontend) lazy load routes to shrink the initial JS chunk
One of the best ways to reduce the size of the initially loaded chunk
(index.js, around 2Mo before optimization) is to lazy load routes and
features so their JS gets isolated in dedicated chunks and is loaded
only when needed.

For example, most of the JS under the legal terms page is never
consulted by users. Likewise, when loading the home page, there is no
need for all the feature-related JS required to display a
videoconference.

After this lazy-loading optimization, the initial chunk is now around
1.2Mo, a significant improvement.
