chore(cpp/vendor): vendor Tabler Icons v3.41.1 (TTF + generador)

Vendorea el set de iconos Tabler (~5500 iconos, MIT) para usar en apps ImGui via icon_font_cpp_core. Incluye: - tabler-icons.ttf — atlas TTF para mergear en ImGui - tabler-icons.css — referencia de codepoints (no se compila) - gen_header.py — script que regenera cpp/functions/core/icons_tabler.h con macros TI_<NAME> a partir del CSS - LICENSE / README.md — atribucion MIT Versionar el TTF (~700 KB) evita depender de descargas en build. Las apps usan TI_* en strings y el atlas se carga con icon_font_cpp_core::load().
