CRITICAL FIX: Correct MySQL memory field extraction

Browse Source 
The calculate_server_capacity() function was extracting the wrong
field from detect_mysql_memory_usage(), causing incorrect available
memory calculations and resulting in 0 max_children recommendations.

Bug: Was extracting field 1 (buffer_pool_mb)
Fix: Now extracts field 3 (estimated_total_mb - actual usage)

detect_mysql_memory_usage returns: buffer_pool|connections|total_mb|status

This fix allows Level 5 optimization to correctly calculate PHP-FPM
capacity and make proper recommendations instead of recommending 0.
