fix: paginate weinfo times and read min deposit from ranking_info

- weinfo.html now pages times with the API's zero-based page offset instead of block heights\n- bal.js renders page metadata and hides dead next links on the last page\n- index.html and terms.html read amount from /ranking_info/{chain}

bal.js
