- Web: a failed CJK font fetch shows English for this session only; the
saved language preference is kept (CjkFontLoader, persisted on save).
- Web fetches the CJK font only when a CJK language (ja) is selected.
- fonts.rs: directory scans match CJK-specific names only (no "noto" or
"gothic"); CJK stays the last fallback after the Latin UI font.
- Revert unrelated clippy rewrites in component_clone.rs, coplanar.rs,
canvas.rs and issue_report.rs to match main.
- Tests: default English, fallback order, CJK-only matching, fetch only
for CJK, failed fetch keeps the saved language.
