refactor: improve alert message formatting

- Refactored the code in `alert_pushover.sh` and `alert_telegram.sh` to improve the formatting of the alert messages.
- Updated the message structure to include the server name before other information.
- Added line breaks for better readability.
- Made sure that all variables are properly interpolated within the messages.
