fix(parsers): resolve shared variables in compose environment

Extract shared variable resolution logic into a reusable helper function
`resolveSharedEnvironmentVariables()` and apply it in applicationParser and
serviceParser to ensure patterns like {{environment.VAR}}, {{project.VAR}},
and {{team.VAR}} are properly resolved in the compose environment section.

Without this, unresolved {{...}} strings would take precedence over resolved
values from the .env file (env_file:) in docker-compose configurations.
