🤨 Rationale

This PR adds the OK search-input component, including the OK web component, Angular wrapper, Storybook coverage, and a small example-client-app integration.

👩‍💻 Implementation

The implementation adds the OK search-input web component in the OK components package, including its template, styles, appearance types, and browser tests.

It adds the matching Angular wrapper entry point for ok-angular/search-input, registers the component in ok-components all-components, and adds a focused example-client-app demo block.

It also adds Storybook stories, matrix coverage, and docs for the new OK search-input component.
