fix(cli): default cli_refresh_interval to 1.0 to keep status bar alive (#49087)

Browse source 
PR #49056 set the default to 0, which reverts the #45592 idle-clock fix:
without a periodic invalidate, prompt_toolkit stops repainting the bottom
chrome during idle and the status bar goes stale/disappears after a turn.

Restore 1.0 as the default for everyone. The config knob stays — users on
emulators where the per-second redraw fights auto-scroll (#48309) can set
display.cli_refresh_interval: 0 to opt out.
