"""JSON plugin-config saves store what the device would load, and only what was sent.

Runs a real ConfigManager and SchemaManager over tmp_path, like
test_api_v3_secret_roundtrip.py, so assertions are on config.json itself.

- POST /plugins/config with a partial ``config`` reset every unsent setting to
  its schema default: the JSON path built on defaults, not the stored section.
- Legacy booleans (#588) were normalized only at load, so posting back what
  GET /plugins/config returned failed validation.
- The JSON save's filter kept only enabled/display_duration/live_priority, so
  a submitted vegas_* tuning key was silently dropped.
- ``skin`` and ``skin_options`` outlived the skin system in stored configs:
  every save path must accept a section carrying them, and drop them.
- Plugin sections posted to /config/main skipped all of that and were stored
  verbatim, including values /plugins/config rejects.
