setConfigFromEnv into a helper to bring the function’s cyclomatic complexity
within the configured limit. Preserve the file override behavior and existing
read-error handling when moving the logic.

- Line 292: Move getValueFromEnvFile out of setConfigFromEnv to package scope,
or define it as a local anonymous function, so the Go code compiles without a
nested named function declaration.
- Line 300: Replace the nonexistent os.GetEnv call in the `_FILE`
environment-variable lookup with the standard-library os.Getenv function,
preserving the existing key and fallback behavior.
- Line 305: In the file-read failure branch of the helper, replace the nil first
return value with an empty string, preserving the existing boolean and wrapped
error. Locate the branch by its “failed to open” error message.
- Line 379: Remove the stray closing brace from the `getValueFromEnvFile`
assignment for `GEOIPUPDATE_PROXY_USER_PASSWORD` so the following error check
remains part of valid syntax.

Suppress the confirmed G703 diagnostic for the operator-selected file path.
The configured Go lint command reports G703 for this os.ReadFile call. The path is intentionally supplied through the environment, so add a targeted suppression with a justification.
Suggested fix
- content, err := os.ReadFile(filepath.Clean(value))
+ content, err := os.ReadFile(filepath.Clean(value)) //nolint:gosec // Path is operator-supplied via environment.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
