Introduce header-based authentication for the n8n webhook request by adding $AuthHeaderName and $AuthHeaderValue, constructing a $Headers hashtable, and passing it to Invoke-RestMethod via the -Headers parameter. Keeps the existing payload (status, service, output) and log retrieval; webhook URL is unchanged.
Standardize formatting across multiple docker-compose.yml files: convert single quotes to double quotes for ports/args, fix inconsistent newlines at EOF, remove trailing spaces and stray blank lines, and tidy comments. Reformat ListSync healthcheck into a YAML sequence for clarity. Remove the obsolete Immich/docker-compose.yml.old file. These are non-functional cleanup changes to improve consistency and readability.
