Preserve merged-track OQL groups when submitting queries from Study View

[Copilot]

Study View accepted merged-track OQL syntax in the input box, but submission rebuilt gene_list from flattened parsed lines, dropping track-group structure/labels before opening Results View. As a result, grouped queries like ["My fav genes" TP53: HOMDEL, BRAF: V600E] were not represented the same way as homepage submissions.

• Submission path alignment (Study View vs homepage)

  • Added a dedicated serializer for Study View submission that prefers the original typed query string (geneQueryStr) when present.
  • Kept a fallback to parsed-line reconstruction only when the text input is empty.

• Store integration

  • Updated StudyViewPageStore.onSubmitQuery() to use the new serializer instead of always joining unparseOQLQueryLine(query) output, which flattened merged groups.

• Regression coverage

  • Added focused specs to ensure merged-track OQL text is preserved verbatim on submission and fallback behavior remains intact.

export function getGeneListForStudyViewSubmission(
    geneQueryStr: string,
    geneQueries: SingleGeneQuery[]
): string {
    const normalizedGeneQueryStr = geneQueryStr.trim();
    if (normalizedGeneQueryStr.length > 0) {
        return normalizedGeneQueryStr;
    }
    return geneQueries.map(query => unparseOQLQueryLine(query)).join('\n');
}
