Add rules action to exclude a message from a conversation

The current options for dealing with unwanted messages like OOO replies are limited to archiving/resolving the conversation or merely tagging the message. For shared inboxes with ticket statuses enabled, the "Archive conversation" action inappropriately updates the ticket status to 'resolved'. Agents need an action to simply ignore an identified message (e.g., an auto-reply ) so it does not reopen a conversation or impact the ticket status and workflow

Introduce a new rule action: "Exclude message from conversation" (or "Ignore message"). When triggered, this action would:

1. Prevent the message from changing the conversation status (e.g., keep a 'Resolved' ticket as 'Resolved').

2. Prevent the message from triggering SLA rules (by excluding the message from the SLA calculation).

3. (optional) Keep the message visible to agents but mark it with a small, persistent icon indicating it was automatically excluded/ignored, providing transparency without disrupting the workflow.
