## Context - Add "Reset to default" for page layout tabs and widgets — backend mutation resets overrides, reactivates deactivated children, and deletes custom children - Fix override write bug where mutating an overridable property (e.g. widget title) on a standard-app entity incorrectly overwrote the base column instead of writing to the overrides JSONB — PageLayoutUpdateService now uses resolveFlatEntityOverridableProperties for accurate diffing and routes properties through sanitizeOverridableEntityInput - Deprecate isOverridden - We need more time to think about this feature. Currently this adds too much complexity for a very small benefit https://github.com/user-attachments/assets/a84546c8-1e15-4d9e-a489-0825cf8b8ed2
