feat: sync API surface with asobi backend

[Taure]

Summary

• Added new REST API classes: AsobiWorlds (list/get/create), AsobiDirectMessages (send/history)
• Added missing query params on matches, matchmaker, tournaments, notifications, inventory
• Added group management methods (UpdateGroup, GetGroupMembers, UpdateMemberRole, RemoveMember)
• Added new models: WorldModels, DirectMessageModels, ConsumeResponse, GroupMember
• Added WS world methods (create, find_or_create, join, leave, input) and SendDm
• Added WS events: OnWorldTick, OnWorldJoined, OnWorldLeft, OnWorldEvent, OnDmMessage, OnDmSent, OnPresenceUpdated
• Fixed inventory.consume and notifications.markRead return types

Test plan

• Verify C# compiles — no errors
• Verify new API methods match backend controller signatures
• Verify WS message types match asobi_ws_handler.erl
• Test against running asobi backend
