fix: separate per-tool import and import-all buttons in MCP server setup

[yanniszhou]

Summary

Fixes #74

The "Import All" (导入全部) button in the MCP Server setup was inside the tool list .map() loop, creating N identical "Import All" buttons — each only importing a single tool, contradicting the label.

Changes

• Each tool row now has an "Import" button (btn-secondary) — imports only that one tool, with try/catch error handling
• Added a single "Import All" button (btn-primary) outside the loop, below the tool list — imports all tools at once, shows a failure summary if any fail, then closes the form

Before / After

Before: N × "Import All" buttons, each importing 1 tool, no error feedback

After:

• N × "Import" buttons (per row, secondary style)
• 1 × "Import All" button (below list, primary style, closes form on completion)

Test plan

• Test connection to an MCP server with multiple tools
• Click "Import" on a single tool row — verify only that tool is imported
• Click "Import All" — verify all tools are imported and form closes
• Click "Import All" again — verify error summary shows duplicate conflicts

功能改进：

• 修复了 MCP 服务器设置中“导入全部”按钮在循环内重复出现的问题。
• 实现了单工具“导入”与全局“导入全部”按钮的分离，逻辑更清晰。
• 增加了批量导入的错误处理逻辑，能够在完成后汇总失败信息，提升了用户体验。

发现的问题：

• 国际化 Key 缺失：在 EnterpriseSettings.tsx 中新增了 enterprise.tools.import 和 enterprise.tools.importFailed，但 PR 并没有在 en.json 和 zh.json 中添加对应的字段。虽然目前有硬编码回退（|| 'Import'），但建议补全以保持一致。

评审结论：
LGTM。代码逻辑正确，修复了 UI 缺陷。建议合并前或合并后补全以下国际化 Key：

"import": "导入",
"importFailed": "导入失败"
