feat: multi-language support for agent search and admin pipeline config

- search_agents now accepts output_language parameter (en/zh-TW/ja)
- Admin Settings: added Pipeline Configuration section (enabled, max_concurrent_stages, default_timeout_secs)
- Admin Settings: search config now includes vlm_output_language dropdown
- Added translations for pipeline config in en/zh-TW/ja locales
- Agent search uses searchConfig.vlm_output_language for output language
