fix: Resolve Docker Secrets from *_FILE variables even if base variable is missing

- Update all() method to check for *_FILE variables and resolve their base variables
- Ensures APP_KEY, DB_PASSWORD, etc. are resolved even if they don't exist in the array
- Two-pass approach: first processes existing variables, second checks for *_FILE patterns
- Fixes issue where APP_KEY was empty even though APP_KEY_FILE existed
