feat: Add /print command for authorized users

This commit introduces a new `/print` command that is restricted to authorized users. The command displays non-sensitive configuration details to administrators.

The main changes are:
- Created `app/modules/print.py` to house the handler for the new command.
- The handler uses the existing `is_admin` function from `app/permissions.py` to check for authorization.
- The command displays the Timezone, Calendar ID, and n8n Webhook URL.
- Integrated the new command into `app/main.py`.
- Updated `tasks.md` to document the new feature.
