The config loader uses string.Template.substitute() to process environment variables in settings.yaml. However, substitute() treats every dollar sign character as a placeholder prefix, causing a hard crash with ValueError when dollar signs appear in regex patterns like file_pattern.
Replaced substitute() with safe_substitute(), which silently leaves unrecognized placeholders as literal text instead of raising an error. Environment variable substitution still works correctly.
Fixes #2349
