Subject: [PATCH] feat(system): show the library location on the legacy admin
 page

A line under the admin page's statistics names the database path and why it is there (ComfyUI's user folder, PROMPT_MANAGER_DATA_DIR, config.json, or the node folder with a pointer to Move library), read once from GET /prompt_manager/system/library.
