Is your feature request related to a problem?

Yes. Clicking "Use this template" on a card in the template catalog redirects the user to the dashboard but does not apply the selected template choice to the active workspace.

Describe the solution you'd like

1. In TemplateCatalog.tsx, update the URL of the "Use this template" button to point to /editor?template=${template.id}.
2. In PortfolioEditorWorkspace.tsx, read the template parameter from the URL on load. If the template parameter is valid, set the active template in the store.
3. Strip the query parameter from the browser address bar once the template has been assigned to prevent it from re-applying on reload.
