Fix Back being trapped on the connecting popup (all three connect flows)

BT Inspector, BLE HID Host and Sensor Dashboard showed a "Connecting..." /
"Discovering..." popup whose Back handler ignored the key, so if a connect or
service discovery ran long the user was stuck until it timed out. Back on that
popup now sets a cancel flag and returns to the scan list immediately; the
worker thread notices the flag when its current operation finishes, drops the
half-made connection and resumes scanning, and the completion handler ignores
the cancelled result instead of jumping into the device/readings view.
