Add multi-row progress display with a global progress barHEADmaster

Replace the single-line progress bar with a terminal renderer that
shows one row per active progress tag. The overall restore step
(Uploading/Verifying filesystem, Flashing firmware) is a reserved
"global" bar that is always drawn first. Per-component bars (e.g.
SEP, RestoreRamDisk) appear below it and disappear when finalized.

- Redraw in place with ANSI cursor movement; clamp line width to the
  terminal width (ioctl on Unix, console API on Windows, with virtual
  terminal mode enabled)
- Erase and redraw the bars around logger() output so log lines no
  longer corrupt the display
- Remove the global bar once a different restore step starts
- When stdout is not a TTY, skip escape codes and print only the
  changed bar, once per 1% step
- Fix progress throttling: lastprog was an int and was compared after
  being overwritten, so granularity was never applied
- RESTORE_STEP_UPLOAD_IMG no longer drives the global bar; it already
  has per-component bars
