UFW rules check and protocol, comment, limit improvement

ufw allow from $PANEL_IP to any port 2222 > /dev/null 2>&1

ufw allow from $PANEL_IP to any port 2222 proto tcp comment 'Panel Connection' > /dev/null 2>&1

Line 2780 in c82d176

if ! ufw allow 22/tcp comment 'SSH' || ! ufw allow 443/tcp comment 'HTTPS' || ! ufw --force enable; then

if ! ufw limit 22/tcp comment 'SSH' || ! ufw allow 443/tcp comment 'HTTPS' || ! ufw --force enable; then

Plus check for SSH ufw rule:
SSH_PORT=$(grep '^Port' /etc/ssh/sshd_config | awk '{print $2}' || :)

if [ -z "$SSH_PORT" ]; then
SSH_PORT=22
fi

if ! sudo ufw status numbered | grep -qw "$SSH_PORT"; then
ufw limit "$SSH_PORT"/tcp comment "SSH" >& /dev/null
fi

By the same logic, I propose to implement a presence check for all other rules.
