Integrates webmail and emailDelivery apps, mail-server and install/upgrade
paths, cyberpanel_ols 2.7.0-style binaries, and v2.4.5 UI patterns while
preserving v2.5.5-dev behavior (SnappyMail/PUBLIC_ROOT, childPath in
launchChild, hardened downloads and SSH activity modal).
- plogical/firewallUtilities: fix inverted success/failure (result==1 = success); write blocked_ips.log under CyberCP/data for cyberpanel write access
- plogical/processUtilities: when root, use normalExecutioner return value so executioner reflects actual command success/failure
- firewall/firewallManager: addBannedIP uses FirewallUtilities.blockIP; ACL and all errors return JSON with error_message/error; rollback store if block fails
- baseTemplate/views: blockIPAddress uses FirewallUtilities.blockIP instead of subprocess
- baseTemplate/homePage: inline Ban IP calls /firewall/addBannedIP with ip/reason/duration; show server error in notifications
- baseTemplate/system-status.js: handle string response and show server error_message in success and error callbacks
- Added configurable compression for database backups using gzip streaming
- Implemented auto-detection in restore function for compressed and uncompressed formats
- Added performance optimizations including --single-transaction and --extended-insert
- Created configuration file for gradual feature rollout with safe defaults
- Added helper functions for checking system capabilities and configuration
- Included comprehensive test suite to verify backward compatibility
- Maintained 100% backward compatibility with existing backup infrastructure
