chore: add Fix repository path

[svienot]

Description:

• add REPOSITORY_PATH_HOST .env variable (cherry pick commit from upstream ethereum/sourcify and use it in hedera specific files)
• align repository mount point inside the server container on what is used in (production) K8S deployment (i.e. /data instead of /home/data/repository)
• adjust network reset script accordingly to enable its use in production.
