Add explicit type definition for ChannelDetails

This change uses an alias (LdkChannelDetails) and an explicit Vec<LdkChannelDetails> type annotation for 'open_channels' in close_channel_internal and update_channel_config. This resolves type ambiguity caused by a name collision with the local ChannelDetails struct, which prevents rust-analyzer from correctly inferring the type as Vec, leading to an incorrect 'len() is private' error.
