Standardizes Dockerfile syntax and enforces queryset ordering

Updates the Dockerfile to use consistent capitalization in the `AS` keyword and modifies the `CMD` instruction to use an array format for better reliability.

Enforces default ordering by `id` for `Employee` and `Department` querysets to ensure consistent API responses.
