Fix stale dotAdmin UVE breadcrumb title on page navigation

[Copilot]

Proposed Changes

• Breadcrumb update timing
  • Make the UVE breadcrumb effect read pageParams().url untracked, so the breadcrumb updates from the newly loaded pageAsset instead of reacting early to route param changes and reusing the previous page title.
• Regression coverage
  • Add a shell-level test that simulates a delayed page load and verifies the breadcrumb is not updated until the new page response arrives.

const currentPageUrl = untracked(() => this.uveStore.pageParams()?.url);

this.#globalStore.addNewBreadcrumb({
    label: page?.title,
    url: currentPageUrl,
    id: `${page?.identifier}`
});

Checklist

• Tests
• Translations
• Security Implications Contemplated (frontend state timing change only; no new data flow or privilege impact)

Additional Info

The issue was caused by the breadcrumb effect depending on both the current page asset and the current page params. During navigation, params changed before the new page response arrived, so the header could momentarily pair the new URL with the previous page title and remain one page behind.

Scope is limited to the UVE shell breadcrumb path; existing breadcrumb behavior for other portlets is untouched.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• opencollective.com
  • Triggering command: /opt/hostedtoolcache/node/24.15.0/x64/bin/node /opt/hostedtoolcache/node/24.15.0/x64/bin/node /home/REDACTED/work/core/core/core-web/node_modules/document-register-element/node_modules/.bin/lightercollective (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
