cschantz 7a68086bf1 Implement all 5 optimization levels with full functionality 
Level 1: max_children optimization (previously done)
Level 2: max_children + memory_limit optimization
- Calculates optimal memory_limit per domain based on traffic
- Finds and modifies php.ini files safely
- Validates changes before applying
- Auto-rollback on errors

Level 3: Advanced - max_children + memory_limit + pm.max_requests
- Includes all Level 2 features
- Adds pm.max_requests for memory leak prevention
- Recycles processes based on traffic patterns
- Comprehensive per-domain optimization

Level 4: OPcache Optimization
- Detects OPcache status per domain
- Enables OPcache on disabled domains
- Sets optimal memory_consumption based on traffic
- Validates PHP syntax after changes

Level 5: Everything - Comprehensive Optimization
- Runs all optimizations in unified flow
- Shows progress for each step
- Provides detailed summary of changes
- Single point to optimize entire server

Helper Functions Added:
- calculate_optimal_memory_limit() - memory per domain
- find_php_ini_files() - locate ini files to modify
- modify_php_ini_setting() - safe ini modification
- validate_php_ini() - syntax validation
- calculate_optimal_max_requests() - process recycling
- is_opcache_enabled() - OPcache status check
- enable_opcache() - enable OPcache
- calculate_optimal_opcache_memory() - Opcache sizing
- rollback_php_ini() - rollback on error

All levels include:
- Backup before modifying
- Validation after changes
- Automatic rollback on failure
- Progress display
- Summary report
