feat(mcp): add MCP runtime configuration

[GatewayJ]

Summary

• Add shared MCP config support across agent profile and hub resource flows.
• Wire MCP config generation into OpenClaw, PicoClaw, and Codex runtime adapters, including remote/stdio server payload handling.
• Improve MCP runtime observability with tool progress handling and timeout behavior.
• Add UI for managing MCP configs, including JSON highlighting and inline JSON validation for MCP resource config editing.
• Document the OpenClaw MCP restart/configuration plan.

MCP light-theme screenshots

Captured from the local CSGClaw service at http://127.0.0.1:18080/ using Playwright MCP. For each screenshot I verified the page state before capture:

• light theme: document.documentElement.dataset.theme === "light"
• Chinese: document.documentElement.lang === "zh-CN"
• English: document.documentElement.lang === "en"

已完成本轮 review 修复并更新分支 docs/openclaw-mcp-restart-plan（commit: 30d5ca8）。

已处理内容：

1. Create 路径也严格拒绝 legacy runtime_options.mcp（与 Update 一致），避免 create/update 行为分裂。
2. 在 CreateAgentSpec.UnmarshalJSON 增加反序列化期校验，避免低层解析后流入服务层。
3. 修正并补充 service 单测，覆盖：
   • runtime_options.mcp 触发显式 deprecation 错误；
   • MCPConfig（top-level mcp_config）正常创建。

影响评估：MCP 功能可用路径（mcp_config）未改动；仅对 deprecated 路径失败 fast fail。架构保持一致，清晰明确。
