Improve Integration Cards (#643)

* Add integration action components and update integration JSON files

- Introduced new action components for Email, Slack, Discord, Webhook, and Google Sheets integrations, enhancing the user interface for managing these integrations.
- Updated the `integrations.json` files to include `actions_file_name` for each integration, linking them to their respective action components.
- Improved the `GoogleSheetsIntegrationActions.vue` component by replacing direct provider information display with a badge for better UI consistency.

These changes aim to streamline integration management and improve the overall user experience.

* Minor UI fixes
