Developer ebeb496c7c CRITICAL FIX: Overhaul PHP-FPM recommendation algorithm for shared hosting safety 
- Fix: Memory-based calculator now accounts for MySQL memory usage
- Fix: Changed safety buffer from 15% to 50% (much more conservative)
- Fix: Hard cap recommendations at 150 max_children per domain on shared hosting
- Fix: Added combined capacity validation to prevent OOM scenarios
- Fix: Use realistic 20MB per process default instead of 1MB
- Fix: Added critical warning when server has <20% RAM headroom
- Feature: Step 2b now validates that combined domain recommendations fit in RAM
- Feature: Automatically scales down recommendations if they exceed 60% of total RAM
- Safety: Previous recommendations of 227 for 8GB server would now be capped at 150

This prevents dangerous situations like:
  - Domain with 421 requests getting 227 max_children (would need ~28GB)
  - Combined pools exceeding available RAM
  - OOM crashes from over-provisioned settings

Tested on 8GB server with 2 domains: Now recommends 105 + 31 instead of 227 + 31
