Scope .hidden class to .uv

[edsilv]

The .hidden class in the UV's css being globally scoped is causing problems when the UV is used in a tailwindcss app because responsive classes like lg:block are being overridden.

[demiankatz]

Is the solution simply to change .hidden to .uv .hidden in

universalviewer/src/content-handlers/iiif/modules/uv-shared-module/css/styles.less

Lines 32 to 34 in 349c062

	.hidden {
	.hidden();
	}
