fix(backend): 旧版对话导入上限从 64 MiB 放宽到 512 MiB - #84

Conversation
LiveAgent 迁移旧对话时，请求里的 source_metadata 会把对话正文再重复两遍， 带内联图片的长对话整体超过 64 MiB，返回 413，用户看到「超出单次导入限制」。 导入是桌面端一次性迁移，上限只用来挡失控请求；512 MiB 仍低于 maxOversizedBodyDrainBytes (1 GiB)，超限时客户端依然能收到可读的 413。

LiveAgent v2 从 1.x 迁移旧对话时，单条对话通过
POST /v1/migrations/liveagent-history一次性导入。前端请求里，source_metadata会把对话正文再重复两遍（original.segments[].messagesJson和segments[].messages_json），所以带内联图片的长对话整体超过 64 MiB，K-brain 返回 413，桌面端显示「对话超过当前 K-brain 的单次导入大小限制」，这条对话无法迁移。用户已实际遇到。改动
maxLegacyHistoryBodyBytes：64 << 20改为512 << 20，并更新注释。TestOversizedJSONBodiesReturnReadable413的期望文案改为512 MiB。导入是桌面端的一次性迁移，这个上限只用来挡失控请求。512 MiB 仍低于
maxOversizedBodyDrainBytes（1 GiB），超限请求依然能收到可读的 413，不会变成连接重置。其他接口的通用 4 MiB 上限不变。验证
go vet ./internal/backendgo test ./internal/backend -count=1：通过（53s），其中包括 513 MiB 超限请求返回可读 413 的用例。LiveAgent 侧会把 K-brain 锁定到包含本改动的版本，并让之前因 413 失败的对话在启动时自动重试一次。
