feat(models): 对齐 vivid 新改动——模型删除改软删,重导不丢计数/定价

- model_configs 加 deleted_at(gorm 软删),List/Get 自动过滤,
  GetAny/Unscoped 用于复活与孤儿清理路径
- 渠道同步/删渠道/管理端删除模型的孤儿清理全部走软删
- 导入时若命中软删行:UpdateAny + deleted_at=NULL 复活,
  generation_count 与原定价保留(vivid a42f32c 同语义)
- provider 时代残留仍物理删除(DeleteHard),不留软删垃圾
- OrphanModelIDs 跳过已软删行,避免重复清扫
- btn-primary 禁用态改浅灰填充(vivid d636105)

核对过已等价的:vivid 僵尸任务兜底(我们的 ResumeStaleJob+
PurgeStale+MarkRefunded 同语义)、产物 MIME 魔数嗅探、
retention 按创建时间、渠道同步弹窗(开关+别名)均已覆盖。

 ## ✨ Introduction
 
 **image2api** is a homogeneous gateway. Upstream, it connects any number of **vivid-protocol (vividai) instances** as "channels" and routes jobs across them. Downstream, it exposes the same **vivid-protocol API** to callers: `POST /v1/generate` (NDJSON stream) · `POST /v1/uploads` (presigned upload) · `GET /v1/models` · `GET /v1/balance`. No built-in provider code, no account pools — an upstream is just another vividai instance, so gateways can be layered arbitrarily.
