cschantz b4e0939595 Add complete PHP configuration file locations for all control panels 
DOCUMENTATION: Comprehensive PHP config hierarchy across all platforms

CRITICAL ADDITION - All Possible php.ini Locations:

**Priority 1 (HIGHEST) - Per-Directory:**
- .user.ini (PHP-FPM, per-directory, reloads every 5min)
- .htaccess with php_value (mod_php ONLY, usually ignored)
- ~/public_html/.user.ini (most common)
- ~/public_html/subdirectory/.user.ini (cascading)

**Priority 2 - User-Specific:**
- ~/public_html/php.ini (some control panels)
- ~/.php/8.2/php.ini (cPanel MultiPHP style)
- ~/etc/php82/php.ini (InterWorx style)
- ~/php.ini (legacy home directory)

**Priority 3 - Pool-Specific:**
- /opt/cpanel/ea-php82/root/etc/php.ini (cPanel EA-PHP)
- /opt/cpanel/ea-php82/root/etc/php.d/*.ini (additional, alphabetical)
- /opt/alt/php82/etc/php.ini (CloudLinux Alt-PHP)
- /var/www/vhosts/system/domain/etc/php.ini (Plesk)
- /home/user/var/domain/etc/php.ini (InterWorx)

**Priority 4 (LOWEST) - System-Wide:**
- /etc/php.ini (global fallback)

**Coverage by Control Panel:**
✅ cPanel with EA-PHP (most common, fully mapped)
✅ CloudLinux with Alt-PHP (fully mapped)
✅ Plesk (all locations documented)
✅ InterWorx (domain-specific paths)
✅ DirectAdmin (user/domain hierarchy)
✅ No control panel (standard paths)

**Universal Detection Function:**
find_all_php_configs() - Scans ALL possible locations
- Checks 15+ location patterns
- Returns priority-ordered list
- Works across all control panels
- Handles version-specific paths

**Effective Setting Detection:**
Method 1: Query PHP directly (MOST ACCURATE!)
  su -s /bin/bash $user -c "php -r 'echo ini_get("setting");'"

Method 2: Parse hierarchy (fallback)
  Priority 4 → 3 → 2 → 1 (higher overrides lower)

**Key Discoveries:**
- .user.ini overrides EVERYTHING (highest priority!)
- .htaccess php_value only works with mod_php (NOT PHP-FPM!)
- cPanel creates user configs in ~/.php/VERSION/php.ini
- public_html/php.ini exists on some configurations
- Multiple .ini files loaded alphabetically in php.d/

**Detection Commands:**
- Find all: find / -name "php.ini" -type f
- Find .user.ini: find /home -name ".user.ini"
- Get effective: php -r "echo ini_get('setting');"
- List loaded: php --ini

This ensures optimizer finds ALL configs affecting each domain!

6. Provide actionable recommendations with safety checks
7. One-click apply with automatic backups

IMPLEMENTATION PHASES:
- Phase 1: lib/php-detector.sh (detection logic)
- Phase 2: lib/php-analyzer.sh (analysis engine)
- Phase 3: modules/performance/php-optimizer.sh (main script)
- Phase 4: Integration with live-attack-monitor
