Pull request overview

This PR adds a bulk "Add to playlist" action to episode lists and the Up Next queue, allowing users to select multiple podcast episodes and add them to playlists. The implementation includes validation to prevent adding custom files or exceeding the 1000-episode playlist limit, along with appropriate analytics tracking for bulk operations.

Changes:

• Added "Add to playlist" toolbar action to multiselect mode for episode lists and Up Next queue
• Refactored AddToPlaylistFragmentFactory to accept a list of episodes instead of a single episode
• Implemented validation to block adding user episodes and enforce the 1000-episode limit
• Added bulk analytics events (EPISODE_ADDED_TO_LIST_BULK and EPISODE_REMOVED_FROM_LIST_BULK)
• Enhanced UI feedback with appropriate error messages for different limit scenarios

That worked great in my testing. There was only a minor issue, when I navigated to Up Next from the full screen player, I didn't see the snackbar warning that playlists can only contain podcast episodes.
