字体 kind 提升为 canonical 并去掉 font 别名

- game_creation_app.rs：`GAME_CREATION_APP_CANONICAL_ASSET_KINDS` 加入 `font`（17 → 18 项），分类表补 `font → document`，删除 `"font" => "document"` 别名。
- gameCreationApp.ts：TS 侧同步加入 `font`、删除别名表条目、补 `font: 'document'` 分类，并同步别名表注释。
- 测试：两侧用例改为断言 `font` 是 canonical 成员（大小写仍不敏感）、栏目仍是 document。
- 理由：字体上传写入侧直接落 `font`，再把它当别名会让「落盘值集合」与「canonical 集合」分叉；严格解析下写入侧的值必须本身就是 canonical。
