chore: rename compose project from pipeline to cht-sync

[mrjones-plip]

Description

Our docker compose project is named pipeline which we don't reference anymore. This also causes containers to be named pipeline-pgadmin etc. which folks may not know is actually cht-sync related:

docker ps --format "table {{.Status}}\t{{.Names}}"        
STATUS                         NAMES
Restarting (1) 4 seconds ago   pipeline-couch2pg-1
Up 21 seconds                  pipeline-pgadmin-1
Up 21 seconds                  pipeline-dbt-1
Up 19 seconds                  pipeline-postgres-1

I think we should comment out the .env project name and add a sane default to the main compose file.

Code review checklist

• Readable: Concise, well named, follows the style guide, documented if necessary.
• Documented: Configuration and user documentation on cht-docs
• Tested: Unit and/or e2e where appropriate
• Backwards compatible: Works with existing data and configuration or includes a migration. Any breaking changes documented in the release notes.
