GameCreationApp 资源 kind 词汇表收敛为 Rust 单源并接上可注册留痕回调

- asset_kind.rs：新增声明宏，由一张 kind 表派生出枚举、线上值 as_str、ALL、严格解析与 ts-rs 绑定，仓库里不再有第二份 kind 列表。
- asset_kind.rs：from_str_lossy 改名 from_str_or_unknown 并去掉 trim / lowercase 归一，parse_with_context 只做严格等值匹配，认不出的原值不查别名、不迁移。
- asset_kind.rs：留痕改为可注册回调 set_non_canonical_asset_kind_reporter，把原始串与调用上下文交给壳层日志，未注册时静默。
- game_creation_app.rs：删除手写 GAME_CREATION_APP_CANONICAL_ASSET_KINDS 与 canonical_game_creation_app_asset_kind 别名表（含 font → document 特例），分类映射表按枚举成员穷举。
- shared-contracts/Cargo.toml：删除 kind-observability feature 与 tracing 依赖，留痕不再靠 tracing。
- api-server/editor_project.rs：图片编辑白名单注释改成「API 兼容面」，不再自称 kind 别名表。
