Fix: Open browser with write_token so trackio show allows mutations

[abidlabs]

Summary

Closes #497.

trackio show always opens the dashboard in read-only mode because the browser is opened with dashboard_url (no write_token) instead of full_url (includes write_token). Without the token, the trackio_write_token cookie is never set, so get_run_mutation_status returns allowed=false and the UI disables Rename/Delete.

This PR switches the browser open and the notebook embed to use full_url, matching the existing docstring that describes full_url as "the full URL including the write token". The print(...) line still shows the tokenless dashboard_url so the token is not leaked to terminal logs.

Changes

• trackio/__init__.py: use full_url in webbrowser.open(...) and utils.embed_url_in_notebook(...).
