Closes: PRO-1545

Please conduct a thorough self-review before opening the PR.

• I am confident that the code works.
• I have updated documentation where appropriate.

Summary

Adds the broker fees to the ChannelAction::CcmTransfer variant and passes them to the swap request.

I will add the migration in the release branch since this is going straight to release/1.5.

Isn't the more correct thing to do here to delete the migration? It'll be applied on 1.5 so we don't need to update this

[msgmaxim]

This is a hotfix and should go directly into 1.5 I believe. My understanding (from chatting with @dandanlen) is that we will integrate this fix (in some form) directly into #5106.

[dandanlen]

Yes, migration should have been deleted. I'll delete this since I think it will be easier to add with/after #5106
