refactor: Remove hardcoded email and improve environment variable handling

- Removed hardcoded email address `hello@ciphervance.com` and replaced it with `SENDER_EMAIL` from environment variables.
- Added `python-dotenv` to load environment variables from `.env` file for better configuration management.
- Removed redundant logging setup and debug statements for cleaner code.
- Simplified the `send_email` function by removing unnecessary logging and debug output.
- Ensured consistent use of environment variables for SMTP settings and recipient email.

This change improves maintainability and security by avoiding hardcoded values and centralizing configuration.
