Using -password-stdin messes up terminal

[bdeboe]

Describe the bug

After using -password-stdin, the zpm terminal no longer functions. I don't see anything I type, nor what up-arrow'ing to the previous commands would do. It still accepts my input, so if I manage to type it right, it does come back with expected command output.

After exiting zpm, the regular IRIS terminal still works as expected, but if I go back into zpm it's still not showing what I type.

To Reproduce

zpm:USER>repo -n ISCINTERNAL -user bdeboe -password-stdin                       
Password:
zpm:USER> <nothing to see here>

System information (please complete the following information):

• IPM version: 0.10.7
• IRIS version: IRIS for Windows (x86-64) 2026.1 (Build 235U) Tue Apr 7 2026 15:21:50 EDT
• OS: Windows

The classic "left secret mode on" - device flag should be managed using patterns from https://community.intersystems.com/post/robust-error-handling-and-cleanup-objectscript so that even if you Ctrl+C out from the password prompt you can see your typing again.
