Enhanced stack limit

[cesarmr-github]

Is your feature request related to a problem? Please describe.
The current stack limit system only supports values from 1 to infinity. This can be frustrating when more detailed control over the maximum stack size is needed.

Describe the solution you'd like
I would like an improved stack limit system that allows setting intermediate values for each item. Additionally, it would be ideal to have a pre-configured default limit for stacks, so there’s no need to configure each item individually unless necessary.

Describe alternatives you've considered
This functionality would enhance the system's flexibility and allow it to adapt to more specific use cases. For instance, setting a limit of 50 for certain consumable items and 10 for rare materials would simplify inventory organization and management.
