Fix: Account for all changed keys in settingsStore.onDidAnyChange

This commit addresses an issue where only the first changed key was being processed when multiple settings were updated simultaneously. The previous implementation used Object.keys(newValue).find() which stops after finding the first difference.

The updated code now iterates through all keys in the newValue object and compares them to their corresponding values in oldValue. This ensures that every changed setting triggers the notifyLaravel function, providing a complete and accurate representation of settings modifications.

Specifically, this change is crucial in scenarios where:

• clear() or reset() are called on the settings store.
• Multiple settings are updated within a single operation.
• The application is running in watch mode, where consistent updates are expected.

The Object.keys(newValue).filter() method now obtains all changed keys, which are each sent to the notifyLaravel to update the backend for each relevant setting.
