浅念 90dcc58c33 feat(uploads): P0-1 batch 4 — server-side duplicate photo detection (409 + force + index)
契约 UploadInitRequest 加 force(bool,仅 owner/admin 跳过查重)。
服务端 init 事务前置查重:同 albumId + uploaderId + bytes 的非 deleted
照片已存在 → 409 PHOTO_DUPLICATE。photos 表加 idx_photos_dedup 索引
(迁移 20260928120000)。
App UploadInitRequest 加 force 字段 + toJson 序列化。
本地查重(层 1)+ 服务端查重(层 2)双层防线到位。

-- P0-1 层 2:服务端查重索引(同相册+上传者+字节数匹配)
-- 命中即 409 PHOTO_DUPLICATE(force=true 且 owner/admin 可跳过)。
