Normalize quoting and whitespace in compose files

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.
