chore(dbi): tune MySQL query sample limits

Adjust MySQL query sample configuration to optimize resource usage:
- Increase MaxRowsPerQuery from 500 to 5000 (aligns with PostgreSQL)
- Decrease MaxQuerySampleCount from 5000 to 1000 (conservative limit)

This balances query plan collection with CloudWatch Logs limits.
