fix: increase Apache MaxRequestWorkers and optimize performance settings

- Increase MaxRequestWorkers from 150 to 400 to prevent "server reached MaxRequestWorkers" errors
- Configure MPM Prefork module with optimized worker settings
- Add AllowEncodedSlashes NoDecode for special characters in filenames
- Increase Redis maxmemory from 512MB to 2GB for better caching
- Extend PHP execution times from 1800s to 7200s for large operations
- Increase MariaDB max_allowed_packet to 1GB for large file uploads

These changes resolve sync failures caused by Apache worker exhaustion.
