feat: repeater VLAN-style region tagging for untagged flood packets

Browse source 
Repeaters with a home region configured now automatically tag untagged
flood packets (ROUTE_TYPE_FLOOD) with the home region's transport code,
converting them to ROUTE_TYPE_TRANSPORT_FLOOD. Also adds TRANSPORT_CODE_ALL
(0xFFFF) as a reserved code that bypasses region filtering, allowing
mesh-wide flooding when explicitly requested.
