[Feature] Expose batch size settings

[rasa-pa]

📄 Description

We cannot adjust or view the batch size used during training.

🎯 Objective

Expose batch size settings in the training configuration workflow so users can select a custom batch size before training.

This setting should be editable through the UI, ideally with recommended default values and warnings when selecting values that may cause out-of-memory issues.

Similar to the #1494

+1, this would be very helpful for better control over training performance and VRAM usage.

Hi @rasa-pa & @jk4e, thanks for raising this feature request. We are actively working on enabling configurable batch size settings as part of the next Geti release. This release is planned in ~1,5 months, so stay tuned!
