Merge the fixed#31 branch (which carries #38's font fallback) and resolve:
- theme.rs: build on #38's fallback_faces/load_fallback instead of the old
load_cjk. The interface language only reorders the two Han entries
(sys-cjk-han-ja / sys-cjk-han-zh; Japanese first for ja, Chinese first
otherwise); Hangul, Thai and Hebrew keep their place. The region-merged
Noto Sans CJK .ttc is loaded once, with the leading language's face index.
- Fonts are rebuilt on a language switch only when the Han order changes
(HanOrder), not on every switch. font_definitions()/setup_context() use
the default order and never read the host locale.
- Tests stay locale-independent (UiState defaults to English; the desktop
app applies the system language). The web build follows the browser
language except CJK, which would render as tofu without system fonts.
- app.language.set error/params list all five codes; engine.commands lists
it. zh/ko/ru gain the keys #31 added (Page Layout|Orientation, display
theme). The Page Layout screen checkbox keeps English "View" via a
"Sheet Options|View" key (was shown as "Screen").
- Coverage test checks zh/ja/ko/Thai/Hebrew/Cyrillic in both the UI and
cell families by comparing glyphs with the tofu glyph.

Blank cell and row repeats that run past 16384 columns / 1048576 rows
(padding from writers with larger sheets) are clipped instead of
rejecting the file; any data or merge past the edge is still an error.
convert() builds its Cell with ..Cell::value(value) so new Cell fields
take their defaults.

Resolves the shared integration points for both formats: combined sniff,
file.open spec, file filters, MCP description, docs. open_bytes now lets
sniffed content (ODS or XLSB) win over the extension.
