fix: restore print after fenn run

[sanmaxdev]

What does this PR do?

Restores Python's original print after Fenn.run() finishes, including when the entrypoint raises unexpectedly. User print() calls are still captured by the Fenn logger while the entrypoint is running, but exception handlers and code after run() now use normal stdout behavior again.

This also clears the configured log file paths when the logger closes so later standalone CLI logging cannot write to stale per-run files.
