fix(footer): align template_1 shell with Zibll 1:1

Rewrite footer markup to zib_footer_con contract: single adaptive logo
(white-src/dark-src), fcode-links HTML primary, float third column,
hidden-xs, toggle-radius contacts, miniimg structure, customize-first
footer-conter. Restyle zibll-shell CSS and drop conflicting site-footer
BEM padding so filled footer data matches Zibll layout.
