refactor(cli): move the live view to cli/display.py and the prompts to cli/prompts.py

- display.py holds the message buffer, layout, status tables and report panels, the analyst wall-time tracker (CLI-only, from graph/analyst_execution) and the one Console
- utils.py is renamed prompts.py, which is what it holds; its analyst list is ANALYST_CHOICES, apart from display's ANALYST_ORDER
- get_initial_analyst_node, a one-line helper with one caller, is inlined
- the wall-time tracker tests sit with the other display tests, and tests import cli.prompts as prompts
