[Bug]: {{project.*}} and {{team.*}} variable interpolation broken in Docker Compose build packs after beta.465 #8932

Error Message and Logs

{{project.*}} and {{team.*}} variable interpolation stopped working for Docker Compose build packs after updating to beta.465+. The literal template string (e.g. {{project.REFRESH_TOKEN_EXPIRY_DAYS}}) is passed to the container instead of the resolved value.

This was working on beta.464 (March 9). After auto-updating through beta.465/466/467, interpolation broke. Suspecting the env var parser change in beta.465 (#8855) may have affected the {{project.*}} syntax.

Expected behavior

Container receives REFRESH_TOKEN_EXPIRY_DAYS=7

Actual behavior

Container receives the literal string {{project.REFRESH_TOKEN_EXPIRY_DAYS}}, causing Pydantic validation errors when the app expects an integer.

Workaround

Hardcoding values directly in the compose app's environment variables instead of using {{project.*}} references.

Steps to Reproduce

1. Create a Docker Compose build pack application
2. Set a project-level environment variable (e.g. REFRESH_TOKEN_EXPIRY_DAYS=7)
3. Reference it in the compose app's env vars as {{project.REFRESH_TOKEN_EXPIRY_DAYS}}
4. Deploy
