fix(views): use createSafeId in custom args tab

crypto.randomUUID() is only defined in secure contexts, so self-hosted
HTTP deployments were throwing TypeError on mount and when clicking Add.
Route the id generation through the existing createSafeId() helper so
the tab works in non-secure contexts too.

Fixes #1214
