fix(frontend): fix search input style for linter dashboard (#3806)

The webpack production build removes type="text" from inputs, since it's
the default and seen as redundant. This broke the styling for the linter
search input, which was using the selector `.search-box
input[type="text"]`.

This PR fixes the issue by updating the selector to `.search-box input`,
which works correctly in all environments without needing complex
Webpack configuration changes.
