[management,signal,proxy,relay,misc] Increase test surface for configuration backwards compatibility

The shared loader changes how each service reads environment variables,
flags and configuration files. These tests assert the behavior main
produced for concrete inputs (env names and aliases, empty and invalid
values, list parsing, flag precedence, file decoding shapes, key
persistence), so every intentional break shows up as a failing test that
can be reviewed and either restored or documented.
