fix: dataset breadcrumb navigation to avoid history back on repeated clicks

[Copilot]

In dataset detail pages, clicking the first breadcrumb (Datasets) could invoke browser history (back) and send users to the previous URL, including external pages. This PR makes breadcrumb navigation deterministic by always routing to the datasets list path.

• Navigation behavior update

  • Replaced history-based handling for the datasets breadcrumb with explicit router navigation.
  • Datasets breadcrumb now consistently resolves to /datasets regardless of prior browser history state.

• Breadcrumb click path consistency

  • Kept existing breadcrumb URL composition flow (url + crumb.url) and applied it to the datasets branch, aligning behavior with the non-datasets branch.

• Focused unit coverage

  • Added a breadcrumb spec asserting repeated clicks on the datasets crumb trigger route navigation to /datasets (instead of history back behavior).

if (crumb.fallback === "/datasets") {
  // previous behavior: this.location.back();
  this.router.navigateByUrl(url + crumb.url);
}
