fix coming soon page: crash, logo centering, admin login link

Add AnalyticsHook to the coming_soon live session — the shop layout
fires an analytics:screen JS event but the session had no handler,
crashing the page on connect.

Centre the logo image (display:block from CSS reset needs
margin-inline:auto). Add a subtle "Admin" link at the bottom using
flex flow rather than fixed/absolute positioning so it works in
iframes.
