[FIX] web: restore HTML report CSS

Steps to reproduce:

- Open base runbot with no installations > Install Account > Check an
invoice preview.
- Install Website > Check invoice preview > It looks narrow and does
not fill the available width.

Starting from [1], the code that sets the `container-fluid` class on
HTML web reports was replaced with the Owl version on the `ReportAction`
[2] but since some reports are not using this system, the code was
restored in a separate JS module.
