Fix issue 2993: Prevent Flow status logs from hiding human input (#2994)

* Fix issue 2993: Prevent Flow status logs from hiding human input

- Add pause_live_updates() and resume_live_updates() methods to ConsoleFormatter
- Modify _ask_human_input() to pause Flow status updates during human input
- Add comprehensive tests for pause/resume functionality and integration
- Ensure Live session is properly managed during human input prompts
- Fix prevents Flow status logs from overwriting user input prompts

Fixes #2993
