- SshSession::resetConnection(): force-disconnect before each new top-level

backup operation so ssh_scp_new() doesn't fail on a reused stale session
  (reproduces as 'Failed to open channel for scp' right after restore)
- Call resetConnection() at entry of createBackup() and uploadBackup()
- Replace recursive findStackView() in PageSetupWizardEasy with upward
  parent traversal (depth+push check) to avoid JS stack overflow on iOS
  when component tree is large (71 VPN managers in test)
