fix(auth): 微信登录按钮放大+主题色 & /api/auth/aggregate 500 诊断日志\n\nUI 改动（微信登录按钮 + 个人页绑定卡片）：\n- OAuthButtons.vue：aggregate 微信按钮 48x48 → 56x56，SVG 图标 22px→28px；默认背景微信绿 #07C160，hover #06ad56，active #059a4c；正常态加绿色阴影，纯 #fff 文字；不再和相邻 Google/GitHub 保持原尺寸不变\n- OAuthBindingCard.vue 个人页卡片：aggregate(aggregate)：微信图标框 40x40→48x48（h-10→h-12），图标 22px→26px，背景/边框/文字用微信绿 #07C160；未绑定微信色 立即绑定微信 按钮 字号从 xs→sm，py 1.5→2.5，文案 立即绑定→立即绑定微信\n\n500 排错日志（/api/auth/aggregate）：\n- loadAggregateSettings：先取 env fallback 前置，DB select 包 try/catch 不抛；并打印 [AggregateOAuth] enabled/appId/appKey 长度/loginType/endpoint 状态(DB=? 配置 / ENV=? 配置 / dbEnabled回退逻辑\n- auxxStrategy.getAuthorizeUrl 全链路结构化日志：\n 1) 参数打印（enabled/endpoint/safe_ok/redirect_uri/state_len\n 2) 配置缺失时逐条枚举原因（APP_ID 空 / APP_KEY 空 / ENDPOINT 空 / enabled=false）\n 3) endpoint 不合法时单独打印 [AggregateOAuth][auxx][getAuthorizeUrl] endpoint 不合法 + JSON(endpoint)\n 4) 请求 auxx.cn/connect.php?act=login 前打印 GET URL（appkey 替换为 ***，日志绝不输出真实密钥）\n 5) $fetch 成功打印 code/msg/has_url/url_prefix\n 6) $fetch 异常打印 err/status/body (response._data 或 data 前 400 字）\n 7) $fetch 加 15000ms 超时，避免 Runner 到 auxx 不通卡死一直挂 30s\n 以上；30s+ 才被 Nitro 强制 500
