 fix(arm64-linux): fix CJK font rendering on flutter-elinux (#15324) 
* fix(arm64-linux): fix CJK font rendering on flutter-elinux

The flutter-elinux engine used for ARM64 Linux builds is compiled without
--enable-fontconfig, so Flutter's text shaper cannot discover system fonts.
This causes CJK characters to render as tofu boxes even when fonts such as
Noto Sans CJK are installed. See flutter/flutter#139293.

Fix by loading a CJK font at startup via FontLoader (bypassing fontconfig)
and propagating it through two paths so all text widgets are covered:

1. MyTheme.applyFontFallback() — updates textTheme on both light and dark
   ThemeData so Material components receive the fallback through the theme.

2. _mergeCjkFallback() in GetMaterialApp builders — wraps child widgets in
   DefaultTextStyle.merge so bare Text() widgets and those with inherit:true
   also render CJK characters correctly.

Font discovery queries fc-list for zh, ja, and ko separately, preferring
fonts present in all three sets (true pan-CJK fonts such as NotoSansCJK or
SourceHanSans) over Chinese-only fonts that may lack Japanese kana or Korean
hangul glyphs.  Falls back to a hardcoded search-path list covering
Debian/Ubuntu, Fedora/RHEL, Arch Linux, and WenQuanYi font layouts.

This is an app-level workaround. The engine-level fix is tracked at
flutter/flutter#180235 (open as of 2026-06).

Fixes #10666
