[Jetcaster] Wear - adds navigation to player, cleanup

[kul3r4]

• Adds navigation to Player from latest episodes and setting the URI via EpisodePlayer
• Cleanup
• Restructured the Dialog for when the content is empty

Are these needed or can these be removed?

let's leave them for now as I will need to add snackbar messages anyway for when added to queues.

This block can be simplified to:

                val podcast = viewState.podcastCategoryFilterResult.topPodcasts.first()
                item {
                    PodcastContent(
                        podcast = podcast,
                        downloadItemArtworkPlaceholder = rememberVectorPainter(
                            image = Icons.Default.MusicNote,
                            tintColor = Color.Blue,
                        ),
                        onClick = {
                            onTogglePodcastFollowed(podcast)
                        },
                    )
                }
