Clicking the File tab now opens a full-window Backstage view in place of the
ribbon, formula bar, grid and sheet tabs, like Excel's. Esc or the back arrow
return to the sheet. Pages: Home (new + recent), New (blank + samples), Open
(recent + Browse), Info (location, properties, Protect Workbook), Save, Save As,
Print (page preview, scope, fit to page, Page Setup), Export (PDF, CSV, web
page), Close and Options (theme, language, formula bar, AutoSave, calculation).
Every action runs an existing command or dialog.
Adds `file.options` (reports the workbook's calculation settings and asks the
interface for the Options page) and the UI command `ui.backstage {page}`.
Keyboard shortcuts and the macOS native menu are unchanged.

- UiState::default() is English: tests, the kittest harness and the
snapshot example no longer depend on the host's locale. The desktop app
alone starts from the system language, when ui.json names no supported
language (first run, an older file, an unknown value).
- An unknown or malformed saved language reads as English instead of
failing the whole UiState and resetting every other preference.
- app.language.set takes {"language": "ja"} (with `code` as an alias, the
name the PR description used); the View combo now uses it via
Language::code(). The app.language.* commands are listed by
engine.commands with the other UI commands and documented in
docs/control-protocol.md.
- Home's text "Orientation" (方向) and Page Layout's print "Orientation"
(印刷の向き) get separate keys through a `context|label` key form.
- Japanese: Hide Rows → 行を表示しない, Trace Dependents → 参照先のトレース;
translate the display-theme combo merged in from main.
- system_theme test: the View tab now has two combo boxes; pick the theme one.
