White-label: title/logo now driven by conf (closes #45)

<title>, the navbar brand text, and the logo were all hardcoded
"Proxy - Theta 42"/"Dynamic Proxy". New conf.name/conf.logo keys
(defaults matching current text/asset) thread through the existing
values object pattern in routes/render.js and routes/docs.js, and
top.ejs now renders <%- name %>/<%- logo %> for the title and a new
navbar logo image.

Footer (copyright, theta42.com link, GitHub/license links) and the
existing favicon.svg are left as-is -- open-source attribution and a
distinct, already-working icon asset, not deployment branding.
