formatSubcategoryName title-cased naively, so section headers read "Ssh",
"Dns", "Libreportal". Add a whole-word acronym/brand map so they render
professionally as "SSH", "DNS", "LibrePortal" (also covers VPN/API/IP/UI/URL/
HTTP(S)/TLS/SSL/WebUI for future files). Composes with stripCategoryPrefix,
which runs after and is case-insensitive.
