feat(chat): route retail lifestone commands

Separate retail client actions, ACE server commands, and ordinary chat at the shared router. Port lifestone/lif/ls from the named retail registry through a typed App controller to game action 0x0063, keep unknown verbs on ACE Talk, and cover both UI backends plus exact outbound bytes.
