fix(backup): a running backup is not "Succeeded", nor an install (#149)

- The Backups panel follows the backup:* socket events: "Running" with the
  app and its percentage while a copy is going, then reads the run log
  again when it ends. It showed the previous run's "Succeeded" until then.
- The progress card titled a backup "Installing Backing up casaos-system":
  backup titles come already worded, and the box is "this box".
- Schedules: "Next" says what the server does (it checks every minute: a
  never-run schedule goes off within a minute of saving, a missed slot is
  caught up within one); app icons that fail to load show the initial;
  truncated names have a tooltip; "apps stopped during the copy" is left
  out when only this box is chosen.
