Title: Missing translation string on Event delete error message

Description:
When attempting to delete an Event that is associated with a Campaign, the system throws an error message with a missing translation string:

admin::app.settings.marketing.events.index.delete-failed-associated-campaigns

Instead of a user-friendly error message, the raw translation key is displayed.

Preconditions:

• Admin user is logged into Krayin CRM.
• At least one Event exists and is associated with a Campaign.

Steps to Reproduce:

1. Go to Dashboard → Settings → Events.
2. Try deleting an Event that is already linked with a Campaign.
3. Observe the error message at the bottom of the screen.

Actual Result:
System displays raw translation key:
admin::app.settings.marketing.events.index.delete-failed-associated-campaigns

Expected Result:
A proper translated user-friendly error message should be shown, e.g.,
Cannot delete event as it is associated with one or more campaigns.
