fix: Enable adding multiple new checklist task definitions dynamically in Admin page

Existing admin creation views for inline checklist task definitions has two issues when adding new task definitions dynamically

1. The JSONSchemaEditor will not work in dynamically added rows
2. ID column value is repeated and when saving violates the primary key constraint.

Both of these issues are resolved by this MR.
