[lsampras]

Type of Change

• Bugfix
• New feature
• Enhancement
• Refactoring
• Dependency updates
• Documentation
• CI/CD

Description

• Add the missing encryption key in docker compose toml file
• Remove the 2-part build for docker-compose servers
• Remove the extra trailing whitespaces throughout the project

Additional Changes

• This PR modifies the API contract
• This PR modifies the database schema
• This PR modifies application configuration/environment variables

Motivation and Context

• The docker_compose.toml file is used for building docker compose images, hence this needs to be regularly updated & kept in sync with the local development counterpart...
• The 2-part docker setup was confusing for most folks unless they dug deep into the parts, reverting it in favor of a simpler (but slower) single part docker step

How did you test it?

• ran the setup locally from scratch
