Live updates during a cycle; Filter & sort dropdown on phones; layout polish

- Worker publishes the rows swept so far every few seconds (LivePublishSeconds)
  with a DataVersion stamp; the dashboard reloads on each new version, so
  tables, the Overview and open dialogs update mid-cycle. Shared files are
  written to a temp file and swapped in, so readers never see half a file.
- Phones / tablets: one Filter & sort button opens a column list instead of a
  row of chips, on every table.
- Details: a wrapped Simple / Advanced toggle sits on the left.
- Card fields: fixed-height dialog; field list and add list share it evenly.
