Describe the bug

iqps-go/backend/src/main.rs

Lines 29 to 30 in 9a49cce

	.rotation(Rotation::DAILY)
	.max_log_files(2) // Keep the last 2 days of logs

tracing-appender is supposed to keep only the last two days of logs but last I checked, it wasn't deleting old logs. I deleted the files, need to check again in a few days.
