[BUG] Multiple checkboxes with same ID are unusable

[kevin-carangeot]

Context

If I have multiple PUIK elements on my page, it is possible for some to share the same ID due to the generateId() function in puik-utils (there is a 1 in 1000 chance, but it still happens 😬).

Steps to Reproduce

1. Create multiple puik-checkbox elements.
2. Reload the page until 2 checkboxes have the same ID.
3. The checkbox becomes unusable when clicking on the label.

Expected Behavior

I should be able to click on any label, and it should check the correct checkbox.

Current Behavior

When I click on a label that shares an ID with another, it checks the wrong checkbox.

Additional Comments

The generateId() function in puik-utils does not generate a unique ID.
A UUID should be generated instead of a random number between 1 and 1000 to ensure it is truly unique.
