feat: books.toml -> books.ini, multi-language (add Latin dialect), config-scoped citation display

books.ini with [en]/[pl]/[la]; parseBooks reads INI (bible drops go-toml).
Latin dialect resolves EF citations (Eccli->Sirach, Apoc->Revelation, Luc...);
sigla_style gains 'latin'. Reading citations now DISPLAY in the configured
sigla (FormatRef(SiglaLang)), not raw English. One-shot books.toml->books.ini
user migration (go-toml now config-only). Web settings editor -> books.ini.
