By being lazy loaded, the DateRangePicker library's CSS files where
loaded after the Odoo specific customizations (bundled in the common
assets), resulting in some CSS rules being overridden by the one from
the library.
This commit fixes it by removing the lazy loading of the library's
(S)CSS to be able to handle their loading order. Also as our
customizations requires SCSS pre-processing, they can't be lazy-loaded.
Note: the library's JS assets are stil lazy loaded to minimize the
performance impact of this change.
