`fitWidth` for `video-miniature`, fluid grid (#2830)

* Fluid abstract video list

* normalize timestamp display on miniatures

* use grid for abstract-video-list

- refactor scss function var to pvar to avoid overriding css variables
- move fluid-grid margins to adapt-margin-content-width mixin for maintainability
- fix video-miniature-name margin-top on small screen

* move sceenratio function in a mixin

* display no miniature avatar in channel videos view
