Refactor start.letsencrypt.sh to improve error handling and logging during certificate issuance

- Added shared volume for temporary output storage
- Implemented logging of letsencrypt output to a file
- Created JSON log entries for certificate creation status
- Improved handling of domain checks and output file initialization
