fix: wrong index in ObjectEditor updateKey causing false 'key exists' error

* fix: wrong index in ObjectEditor updateKey causing false 'key exists' error

* fix: same index mismatch issue in updateJSON

* fix(ui): stabilize ObjectEditor pair keys

Use generated ids for key-value pairs instead of array indexes to
prevent mismatch issues during editing and rendering.

Also replace duplicate-key alerts with toast warnings for a more
consistent UI experience.
