[AND-15] Moderation V2

[VelikovPetar]

🎯 Goal

Add handling for the new moderation property of the Message object - in addition to the current moderationDetails.

Linear: https://linear.app/stream/issue/AND-15/moderation-v2

🛠 Implementation details

• Implement new DownstreamModerationDto and include it in the DownstreamMessageDto (+ corresponding domain models and DB entities)
• Modify the Message.isModerationBounce() method to also check if message.moderation.action == ModerationAction.bounce
• Modify the Message.isModerationFlag() method to also check if message.moderation.action == ModerationAction.flag (not used at the moment)
• No need for special handling if action == remove, it is handled automatically via am error message

🎨 UI Changes

Before (bounce -> remove) => Bounce not properly handled when delivered in `moderation`	After (bounce -> remove) => Bounce handled when delivered in `moderation`
bounce_before.mp4	bounce_after.mp4
