Agent Execution UX Improvements: Re-run Button and Batch Ticket Processing

It would be useful for development and testing to improve the current “run agent on ticket” workflow to support faster iteration and batch testing.

Right now, running an agent requires manually entering a ticket ID each time. When doing iterative testing or refining prompts against a single ticket, it would be much more efficient to have a “Re-run” button directly on the ticket. This would immediately reprocess the same ticket through the agent without requiring re-entry of the ticket ID, making rapid testing and debugging much smoother.

In addition, it would be helpful to support batch execution by allowing a comma-separated list of ticket IDs in the run field. This would let multiple tickets be processed in one action, such as three different scenarios or edge cases, and return results for each sequentially or in parallel. This would significantly speed up testing across varied ticket types and reduce repetitive manual execution when validating agent behavior.
