Refactor: Convert ChannelInfoMemberViewController.state to use stateIn

This commit refactors the `state` property in `ChannelInfoMemberViewController` to utilize the `stateIn` operator. This simplifies the state management by directly transforming the upstream flow into a `StateFlow`.

The `onChannelInfoData` function is removed as its logic is now incorporated into the `map` operation within the `stateIn` flow.
