fix: Parse search API response structure correctly

The search API returns {results: [...], count, limit, offset} not just an array.

Fixed in:
- test.html: testSearch(), testSearchWithSource(), testBrowse()
- api.ts: searchSeries(), browseBySource()
- Google Sheets Code.ts: searchSeries(), browseBySource()

Now correctly checks data.results && Array.isArray(data.results) instead of Array.isArray(data).
This was causing tests to fail even with HTTP 200/208 status codes.
