[BUG] Default sizing and font definitions are overriden by Autocomplete

[AMoo-Miki]

What is the bug?
The overriding of the default styling handed down by OUI produces inconsistent UX.

dashboards-observability/public/components/common/search/search.scss

Lines 26 to 35 in 34068f1

	#autocomplete-textarea {
	width: 100%;
	outline: none;
	min-height: 40px;
	max-width: unset;
	height: 45px;
	resize: vertical;
	font-size: 16px;
	padding-right: 40px;
	}

and

dashboards-observability/public/components/common/search/autocomplete.tsx

Line 142 in 3d754d5

style={{ marginTop: '0px', height: '18px', padding: '8px' }}
