feat: custom prefix system protocol layer

Prefix parsers, composers and events:
- UserPrefixesParser, PrefixReceivedParser, ActivePrefixUpdatedParser
- PurchasePrefixComposer, SetActivePrefixComposer, DeletePrefixComposer, RequestPrefixesComposer
- RoomUnitChatParser reads prefixText/Color/Icon/Effect from chat packets
- RoomSessionChatEvent carries prefix data to client
- RoomChatHandler passes prefix fields through event chain
