conf.name was already plumbed into routes/index.js's values object, but never actually rendered anywhere -- <title>, the navbar brand, and the favicon were all still hardcoded "SSO - Theta 42"/"SSO Manager". Now render <%- name %>/<%- logo %> in top.ejs; new conf.logo key (default: the existing theta42.svg) drives the navbar image and favicon. Also fixes a pre-existing broken favicon: top.ejs referenced /static/favicon.svg, which was never actually served from public/ -- only public/img/theta42.svg existed. The favicon now uses that same file via conf.logo instead of a nonexistent path. Footer copyright/logo/GitHub links are left as-is (open-source attribution, not deployment branding).
