Epic: Messages: New Observability features for streaming

[Haarolean]

This is an epic to track progress on introducing more observability-focused features to messages functionality.

The list:

• Replay messages from the topics (the same topic and from a different one) (possibly edit them before producing) #247
• Load messages from a file
• paste from the clipboard
• Bulk produce
