BgFilter 生产超时同步到 180s，与代码默认值/文档对齐

代码默认已改 180s（14a5cde9d，适配 2K 图），但 env.example 与 deploy/provision
脚本仍写 45000，会被注入生产 env 覆盖默认值，2K BgFilter 仍可能超时。
- 两份 api-server.env.example: 45000 -> 180000
- deploy/provision 脚本改用 ensure_env_value_migrates_old_default，
  把存量机器的旧默认 45000 迁移到 180000（key 缺失则直接写 180000）
