Replace std::string members with StringRef for Application::name_ and Application::friendly_name_. These are set once during setup() and never modified, so std::string overhead is unnecessary. For the MAC suffix case, codegen emits static mutable char buffers with a placeholder suffix that pre_setup() overwrites with the actual MAC address. For the non-suffix case, StringRef points directly at the string literal. Saves ~2.5KB flash and ~48 bytes RAM by eliminating std::string template instantiations (constructor, _M_assign, _M_dispose, _M_construct, _M_replace_cold, _S_copy).
