Feat: improve CLI node evaluation error display

[treysp]

CLI currently prints duplicate/unnecessary error information when a a node evaluation error occurs.

This PR removes the duplication, the unnecessary information, and improves error message formatting.

Background

We currently use multiple approaches to print errors to CLI:

1. console.log_error() is a method we defined to print red text to CLI
2. logger.error() is a standard method that prints to both CLI output and log
3. Standard Python error printing with raise and/or use of Click.ClickException()

Calls to these are spread out, can be duplicative, and do not format the displayed error.

Changes

This PR resolves this by separating these three actions:

1. Print only formatted errors to CLI:
   • All formatting in console methods log_failed_models() and log_skipped_models()
2. Print full error traceback to logger: logger.info() so it doesn't also print to CLI
3. Creates new error class PythonModelEvalError to differentiate from SQL eval errors
