Saving Modal Without Changes – Backend Validation

[Nickzlos]

Description

Currently it’s possible to save modals even when no changes have been made.
We need a backend-side validation to check whether any data has actually changed before triggering processes that normally run when important content is updated. This is especially important for changes via API.

Acceptance Criteria

• When a user clicks “Save” on a modal, the backend compares the submitted data with the existing data.
• If no differences are found, the backend should skip any update-related processes (e.g., events, notifications, or database writes)
• If differences are found, the normal update flow proceeds.

Additional Notes

Ensure that the comparison logic accounts for insignificant changes (e.g., whitespace or formatting) so that only meaningful differences trigger an update.
