v0.98.12

Added

• db dump and db download now say how far they have got instead of spinning
  silently. A dump reports its phase and byte count — dumping — 25.3 GB written,
  compressing — 2.9 GB of 23.6 GB, uploading — 3.6 GB — read from the sizes of
  the two temp files it writes, sampled by the poll that was already asking the
  container whether the job had finished. A download reports 1.9 GB of 3.8 GB (50%). Shown on the TUI status line, and in place on the CLI when stderr is a
  terminal (silent when redirected, so logs stay clean).
