Separate pause/resume buttons, fix hybrid extraction during pause

- Pause button is now one-way (orange glow when paused, disabled when
  already paused). Start button resumes from pause.
- Fix hybrid extraction attempting incomplete multi-part archives when
  paused: disk-fallback now blocks any non-terminal item status, not
  just downloading/validating/integrity_check.
