Mobile Phase 8i: bottom-tab SVG line-icons + ·Ten31· top-bar wordmark

Replace the four bottom-tab emoji glyphs with the dc tabIcon SVGs
(BottomTabIcon, currentColor so they flip with active/theme) and add the
·Ten31· mobile-wordmark to the top bar, making the page title desktop-only.
Closes S1/S2 — Phase 8 (8a–8i) complete; next is deploy + device-test.
