[codex] fix MCP management lifecycle (#1144)

* feat(mcp): add MCP server management UI

- Server CRUD: add/edit/remove with YAML/JSON Monaco editor
- raw_config passthrough: zero field loss on edit/toggle
- tool_details embedding: single-request card data (1+N → 1)
- Auto-retry exponential backoff (2s→32s, max 5 retries)
- Route safety guards (hasRoute) for dynamic sidebar
- i18n: 9 languages (de/en/es/fr/ja/ko/pt/zh/zh-TW)
- 19 unit tests + 8 UX browser tests
- 35 files, +2933 lines

* fix mcp management lifecycle
