Aligning to WikimediaUI style guide by replacing colors with
standard color palette equivalents, merging close colors
(ex: `#E6E6E6` & `#eee` become `#eaecf0` ) and slightly increase
contrast on a few to meet WCAG 2.0 level AA criteria.
Also:
- following other code bases like MobileFrontend or OOjs UI in
using `border-radius` property instead of obsolete mixin
- removing non-existing browser vendor prefixes in mixins
- removing non-used Less variables
- bringing CSS/Less code closer to coding standards and
- simplifying Less code where applicable

Replacing colors with ones from current WCAG 2.0 level AA compliant
color palette. Also improving SVG files by svgo optimization where
easily applicable and cleaning up some minor Less shortcomings.
Bug: T149769

I decided to fix them all at once since we're merging all of these
patches together anyway. I can pull changes into other patches if
absolutely necessary.
Also fixes the dialog open/close handlers for the canvas click event,
and leaves the reuse dialog open on next/prev.
