feat: add UUIDs and URLs to webhook notifications

- Add resource UUIDs (application_uuid, database_uuid, server_uuid, task_uuid) to all webhook notifications
- Standardize URL field naming from various formats (resource_url, task_url, server_url) to consistent 'url' field
- Include parent resource UUIDs for scheduled tasks (application_uuid or service_uuid)
- Add direct URLs to Coolify resources for all notification types
- Update UI to show "Webhook URL (POST)" label for clarity

This enables webhook consumers to:
- Uniquely identify resources using UUIDs used throughout Coolify UI
- Directly link back to Coolify resource pages via the url field
