Retain header/upper section in embedded views when navigating filtered routes with full=true

Description: As an embedded app consumer, I want the full header/upper section (e.g., greeting bar and visuals) to persist when using full=true and navigating to category-filtered routes or sections, so that the presentation remains consistent across per-service pages. Problem: When embedding with full=true, the header/upper visuals render on initial load, but navigating to filtered sections/routes (for example, applying a category filter or opening a feedback section) causes the header to disappear. It only returns on a Back action. Current workarounds either remove the header (embedding without full) or lose filtering/deep links, resulting in an inconsistent experience. Benefit: A persistent header in filtered/deep-linked embedded views delivers a stable, branded experience, improves user orientation and trust, and reduces context switching. It enables consistent per-service feedback pages without custom wrappers or sacrificing filtering.
