Runs smoke tests for all annotations registered to struct_name against a deserialized config struct T.

Verifies three properties:

Supported keys: loading the struct with the test value set via the annotation’s yaml_path and via each of its effective env vars must all produce identical structs, and each must differ from the default (empty-config) struct.

Unsupported keys: loading the struct with that key set must produce a struct identical to the default struct.

Full field coverage: loading the struct with all supported keys set simultaneously must produce a struct where every serialized leaf field differs from the default.

key_aliases and provider_factory configure the test config loader. Pass the same aliases and remapper factory used in production config loading.
