fix(q-dev): auto-scan logging path without extra config

Kiro exports to two well-known S3 prefixes in the same bucket:
- user-report/AWSLogs/{accountId}/KiroLogs/ (CSV reports)
- logging/AWSLogs/{accountId}/KiroLogs/ (interaction logs)

When AccountId is set, automatically scan both paths. The "logging"
prefix is hardcoded since it's a standard Kiro export convention.
No additional configuration needed.
