贴纸配置瘦身：只保留 title/sticker_id/image_url 三个字段。

config/sticker.json 从 58MB / 135 万行降到 22MB / 7.9 万行，79,368 条条目数
与顺序均不变。删掉的字段及依据：

- preview_cover：全部 79,368 条均为空串，零信息。
- sticker_package（含 height_per_frame/size/width_per_frame）与 sticker_type：
  无任何代码读取。add_sticker 完全不读本配置，它只用调用方传入的 sticker_id，
  草稿素材是极简的（id/resource_id/sticker_id/source_platform/type）。
- track_thumbnail：与 large_image 是同一素材的 120×120 与 1920×1920 两种尺寸，
  但签名不同、无法互相推导，本次一并去掉。

保留的三个字段构成检索到使用的完整链路：title 是唯一的搜索键，sticker_id 是
add_sticker 唯一需要的入参，image_url 供调用方展示预览。

顺带把序列化格式改为一条一行（原为 indent=2，每条 4 行），与
config/text_template.json 的大清单一风格一致，便于 diff。

这是对外契约变更：响应由嵌套（sticker.large_image.image_url）改为扁平
（image_url），故同步更新 schemas/search_sticker.py（StickerItem 拉平，
StickerInfo/StickerPackage/LargeImage 三个类删除）、双语文档（含旧版本字段
说明与调用方调整提示）与 openapi.yaml（8 个响应示例 + 响应结构定义）。
service/search_sticker.py 删掉一行死 import：它导入了上述四个类，实际一个都
没用到，删类后会直接 ImportError。

tools/query_sticker.py 新增 flatten_sticker()：上游返回的仍是嵌套结构，不转换
的话工具产出的文件与新配置格式对不上；对已是扁平的输入幂等，缺 title/sticker_id
的条目跳过并计数。

无损验证：79,368 条逐条比对 title/sticker_id/image_url 全部一致，条目顺序一致；
openapi.yaml 的 8 个示例同样逐条比对一致。测试 56 项通过（3 个贴纸 + 53 个字幕/
模板/气泡），端到端 SearchStickerResponse 校验通过。

已知事项：image_url 是带签名的临时 URL，有效期至 2026-12-15，到期后预览图失效
（title/sticker_id 不受影响，add_sticker 不依赖该字段），届时需重新抓取。
