fix(cli): route /sessions and /history through prompt_toolkit-safe printing

Browse source 
Bare print() output is swallowed by patch_stdout while an interactive
prompt_toolkit Application owns the terminal, so /sessions and /history
rendered nothing. Route those emissions through _cprint (prompt_toolkit's
native renderer) when an app is running, and fall back to print otherwise.

Fixes #36815
