laoyang f1a81cbaa1 RAM 角色自动探测 + 邮件配置界面 + 每个软件独立主题色 (#1 #2)
## 1. ECS RAM 角色改为自动探测
原先要用户去阿里云控制台查「实例 RAM 角色名」再手填,纯属多余 ——
机器自己知道答案。

新增 fb_oss_detect_instance_role():读元数据
GET /latest/meta-data/ram/security-credentials/(末尾带斜杠)拿到角色名列表。
- 兼容单行 / 多行 / JSON 数组三种返回
- 未配置角色时 fb_oss_instance_creds() 自动探测,不再报「未配置」
- 后台改成只读展示「已绑定:xxx」,手填入口收进「高级」折叠里
- 保存时留空 = 自动探测后写入,不存空值
- 探测失败给出可操作原因(没绑角色 / 不在 ECS 上 / 元数据被禁用)

## 2. 邮件配置界面(原先完全缺失)
lib/mailer.php 有完整 SMTP 实现,但后台一个输入框都没有,
只能改 config.php —— 用户装完根本找不到地方配。

根因有两层:
- fb_setting_keys() 白名单里没有任何 smtp.* / notify.* 键,
  就算加了表单,fb_set_setting() 也会把值全部丢弃
- 设置页只有「站点信息」「附件存储」两个区块

补上:白名单 15 个键 + 后台「邮件通知」区块
- SMTP 服务器/端口/加密方式(SSL/STARTTLS/不加密)
- 登录账号/密码(留空不修改,避免每次重填)
- 发件地址/显示名、超时、SSL 校验
- 通知规则:回复通知、每次回复都通知、新反馈通知管理员、发信冷却
- 「发送测试邮件」按钮,AJAX 发完就地显示成功或失败原因,
  不用保存再靠猜

## 3. 每个软件一个主题色
需求:从短链接进不同软件,颜色不同,一眼区分。

- software 表加 color 字段(幂等迁移)
- 全站配色靠 --brand / --brand-600 / --brand-soft 三个变量,
  按软件覆写这三个即可,不用为每个软件写一套 CSS
- fb_color_variants() 由主色推出深一档(×0.85)与浅一档(往白混 88%)
- 未配色的软件按 id 从 8 色调色板取默认色,保证同站不撞色
- 后台:颜色选择器(原生取色 + 8 个预设 + 用默认)
- 前台:index / new / thread 都按当前软件注入主题色,
  meta theme-color 也跟着变

验证:三功能专项 30/30;新旧回归全过
(全新安装 33/33、老基线 25/25、附件 22/22、安装向导 60/60、约束检查 20/20)
