feature(serenitea pot): Implementation of the entry function

[Yazawazi]

Description

Working on implementing the functionality to enter the teapot. Currently planning to code the realm selection aspect of the teapot, which may take some time (since I'm not always available, sorry).

Also, there may be a need to fix the error in the proto I submitted in my last PR (#837) because of the wrong CmdId and incorrect field order for some of the protos.

Issues fixed by this PR

Now you can use the serenitea pot and select a realm and enter it.
However, it has a problem that are waiting to be fixed:

- [ ] the selection screen still exists when you use the serenitea pot again after selecting a realm.
Possible causes:
1. the relevant requests and responses are not handled correctly.
It may be in HandlerWidgetDoBagReq, PacketPlayerHomeCompInfoNotify or PacketHomeComfortInfoNotify, or there may be other packets to send.

2. there is a problem with the logic associated with the serenitea pot to place or send Home information.
Packets about Home may need to be verified by capturing the packet again, or there may be a problem with teapot Entity generation.
Headache, keep it like this for now, fix the logic later, sorry
