Move CSSX rules to <head>, skip client-affinity components in SSR

Browse Source 
- Shell inlines CSSX flush logic in <head> (collected/clear-collected!)
  so island CSS rules survive #main-panel morphs during SPA navigation
- OCaml render_to_html skips :affinity :client components during
  Phase 1b SSR (prevents ~cssx/flush rendering inside body-html)
