Prevent OS sleep and display blanking while SDR is running

Add PowerInhibit.pas with InhibitSleep/UninhibitSleep:
- Windows: SetThreadExecutionState (kernel32, no child process)
- macOS: caffeinate -d -i -s -w <PID> (auto-exits on crash via -w flag)
- Linux: systemd-inhibit with kill-0 poll loop (releases within 5s on crash)
