fix: emit console.log on fuzz test last run at verbosity >= 2

[avorylli]

Fixes #11039

Always collect logs from the last fuzz run and include them in results when show_logs: false, enabling display at verbosity >= 2. Preserves existing behavior when show_logs: true.

ideally the logs for the last run are present in logs. currently they are not, which is what the bug is about. is there any reason we can't do that you came across?

[avorylli]

My bad, its actually better to do as you described. Last run logs are now always stored in test_data.logs.

Removed last_run_logs - when show_logs is false, we replace logs with each run's logs, keeping only the last one.
