i18n: add Bulgarian (bg) interface translation (#825)

* i18n: add Bulgarian (bg) interface translation A 2,386-entry Bulgarian catalog: every key of the reference catalog, the equation gallery's labels and everything the interface audit finds. Written from the meaning of the English labels in ordinary Bulgarian computing vocabulary; no other product's localisation and no other catalog in this repository was used. Counts use count-neutral wording ("Думи: 21"). - bg, bg-BG, bg_BG.UTF-8 select it automatically; "Български" in Options and ui.language with {"value":"bg"}. - The interface audit checks Bulgarian coverage the way it checks Russian. - Tests: locales and saved preference, catalog coverage and key translations, count wording, and the bundled Inter/JetBrains Mono faces covering the Bulgarian letters. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Review fixes for #825: Bulgarian built-in style names Adds the built-in style names Russian translates (Normal Table, Default Paragraph Font, Annotation Text/Reference/Subject, Envelope Address/Return, Index Heading, Index {n}, Line Number, Normal Indent, Table of Figures, TOA Heading, TOC {n}) and Good afternoon; updates the entry count in the docs.
