feat(10-01): add 21 new TrafficClass constants and update AllClasses()

- Add constants for Mail (IMAP, POP3, SMTP-sub), File Transfer (FTP, SMB, TFTP)
- Add constants for Remote Access (RDP, Telnet, VNC), Database (MySQL, PostgreSQL, Redis, MongoDB)
- Add constants for Discovery (mDNS, SSDP, SNMP), VoIP (SIP), Web (QUIC)
- Add constants for Infrastructure extension (LDAP, Kerberos, Syslog)
- Update AllClasses() to return 32 classes (LDAP/Kerberos/Syslog excluded per D-01)
