DELETE /destinations response inconsistent with DELETE /tenants

[alexluong]

Summary

DELETE /tenants/{tenant_id} returns { "success": true } (SuccessResponse), but DELETE /tenants/{tenant_id}/destinations/{destination_id} returns the full Destination object.

The OpenAPI spec documents both as returning SuccessResponse, but the destination delete handler actually returns the deleted destination.

Current behavior

DELETE /tenants/{tid} — tenant_handlers.go

c.JSON(http.StatusOK, gin.H{"success": true})

DELETE /tenants/{tid}/destinations/{did} — destination_handlers.go

c.JSON(http.StatusOK, display) // returns full DestinationDisplay

Options

1. Fix code — Change destination delete to return { "success": true } to match the tenant pattern and the current OpenAPI spec
2. Fix spec — Update the OpenAPI spec to document that destination delete returns the full Destination object (useful if callers want to confirm what was deleted)

Context

Found during a full OpenAPI spec audit against the implementation.
