merge: 合并 upstream/main 并解决冲突
解决了以下文件的冲突： - backend/internal/handler/admin/setting_handler.go - 采用 upstream 的字段对齐风格和 *Configured 字段名 - 添加 EnableIdentityPatch 和 IdentityPatchPrompt 字段 - backend/internal/handler/gateway_handler.go - 采用 upstream 的 billingErrorDetails 错误处理方式 - frontend/src/api/admin/settings.ts - 采用 upstream 的 *_configured 字段名 - 添加 enable_identity_patch 和 identity_patch_prompt 字段 - frontend/src/views/admin/SettingsView.vue - 合并 turnstile_secret_key_configured 字段 - 保留 enable_identity_patch 和 identity_patch_prompt 字段
