Merge the fixed#104 branch (which carries #31 and #38) and restructure
the Brazilian Portuguese language onto its per-language layout:
- The PORTUGUESE table moves, unchanged, to crates/ui-egui/src/i18n/pt.rs
as pt::translate, like zh/ko/ru. Language::PtBr gets code() "pt"
(parse also accepts pt-BR/pt_BR via the tag reduction); it is still
saved as "pt".
- No per-language command: the View combo and the control channel switch
with app.language.set {"language": "pt"} (app.language.portuguese is
dropped); error text, engine.commands params and the snapshot example
list every code.
- pt.rs covers the keys added since (Page Layout|Orientation, the display
theme combo, and the Sheet Options View/Print checkboxes, Exibir /
Imprimir); the coverage test checks pt like zh/ko/ru.
- people.toml keeps both new contributor entries.
