fix: prod login + env-file driven config + scroll-snap bounce

- env: 解封 .env / .env.production 提交, 仅忽略 .env.local 系列;
  .env.production 承载 DATABASE_URL / AUTH_SECRET / AUTH_URL /
  SMS_* / NEXT_PUBLIC_TOS_DOMAIN, Dockerfile runner 阶段 COPY 进
  运行时镜像, Next.js standalone 启动自动加载
- ci: 移除 kubectl 注入 secret 步骤(env 已烧入镜像), 保留占位避免
  envFrom optional 引用告警, 修复 /api/auth/providers 500 (缺 AUTH_SECRET)
- auth: signIn 失败透传 NextAuth 真实错误码, 不再被"验证码错误"一刀切掩盖
- home: 首页 scroll-snap-type 由 mandatory 改 proximity, 修复滚动到
  底部被强制吸回候选区顶部的回弹
