fix(relations): use javascript onclick instead of htmx on:click

[b1rger]

This makes the trigger also work with a strict CSP that does not allow
unsafe-eval.

Closes: #1265

Not able to test my ontology with 429cee5 due to an unrelated error - see below. It didn't come up in release 0.28.0, so I applied your change to list_relations template locally and it works. The dialog appears with a thick black border but I guess we can sort that out with styles. Thanks a lot @b1rger

Could you try with Django 5?

Could you try with Django 5?

Constrained because

apis-highlighter-ng (0.3.1) depends on Django (>=4.1,<5.0), 
apis-highlighter-ng (>=0.3.1,<0.3.2 || >0.3.2,<0.4.0) requires Django (>=4.1,<5.0).

Updated my comment - I went back to release 28 and applied this change alone; it works!

Works, thank you!
