Add unique CWKPQ expedition messages to other bosses

First off, sorry for the potentially awful title. Not sure how else to word it.

Currently in CWKPQ, there's a few unique chat messages that get displayed globally when inside which i think are unique to cwkpq? idk, mostly notifications for something happening with a specific player, such as dying, disconnecting, or even just entering the expedition.

Not a particularly important addition, mostly just a bit of QoL, but I think there's a few bosses where these messages could be nice to have. For example, in bosses where there's a high player count with multiple parties, such as HT or PB, or just bosses in general where the party is close together spamming all their skill effects and cash shop effects, the disconnection message could be a fast and easy way to know asap that a player disconnected or died amidst all the chaos.
