Fix ridiculously small font size in overlays under MonoBook

Checked in betalabs useskin=monobook: it seems that vi-ui-overlay 127%; when applied to text in dialogs still gets overwritten with em settings from

body
font: x-small sans-serif;

For example

.ve-ui-mwMediaSearchWidget-noresults {
padding-top: 1em;
}

or
.ve-ui-mwSaveDialog-license {
font-size: 0.85em;

Transclusion box(template) font still looks extremely small.

Yes, it should be the same size as normal monobook text, which is small. But not as small as it was before the change here.

https://www.mediawiki.org/wiki/File:Save_page_by_skins.png was actually comparing Monobook and Vector Save dialogues.

The fix applies to the following dialog boxes

• Save
• Insert-Media
• Insert-References list
• Cite-Basic

Template, Cite-Website, Book, News, Journal still display x-small font-size - bug T75800.
Also, Cancel button in the above mentioned dialog boxes does not work - bug T75802.
