Summary

Add a feature to the Hoppscotch Collection Runner UI to specify the number of iterations for a run, similar to the existing functionality available in the CLI.

Why should this be worked on?

The CLI already supports specifying the number of iterations when running a collection, which is great for automation and scripting. However, users who rely on the UI lack an intuitive way to repeat a collection run multiple times without manually re-triggering it.

Adding this to the UI would significantly improve usability and bring feature parity with the CLI. It would make the tool more friendly for less technical users and enable common workflows such as load testing, mass resource creation, and regression or flakiness testing through the UI.
