Improved experience for AI share message generation

To generate relevant share messages, our AI needs context about the content being shared.

Previously, this context was automatically derived from the preview description of the shared content.

To improve message quality and give managers more control, we’ve introduced a dedicated context field.

With this update:

• The AI now uses this specific context field to understand the content.
• Managers can review and edit the context when needed.
• Share messages become more accurate and aligned with the intended message.
