⚡ Update for VeloCity-Security NotificationCommand

✅ Fixes & Improvements

• Fixed NullPointerException when using /velocitysecurity iptables if entries in the config (ip-block-success-message, ip-unblock-message, etc.) were missing.
• All messages in VelocityNotificationCommand.yml now have safe default values → no more crashes if entries are missing.
• Added whitelist support with customizable message.
• Improved config loader: every text is editable, defaults are applied automatically if missing.
  

⚡ Correct command to block an IP:

/velocitysecurity iptables <IP-Address> <Duration>

Duration formats:

• m → minutes
• h → hours
• d → days
  

Examples:

• /velocitysecurity iptables xx.xxx.xxx.xxx 1m → blocks the IP for 1 minute
• /velocitysecurity iptables xx.xxx.xxx.xxx 2h → blocks the IP for 2 hours
• /velocitysecurity iptables xx.xxx.xxx.xxx 1d → blocks the IP for 1 day
  

⚠️ Important Notice:
After updating, please delete or regenerate the file
plugins/Velocity-Security/VelocityNotificationCommand.yml
so that all new default messages and the whitelist are created correctly.
