[store_yaml] Address review: ConfigType typing and drop redundant priority override

- Annotate `_final_validate` and `to_code` with `ConfigType` parameter and
  return types.
- Drop the `get_setup_priority()` override on `StoreYamlComponent`; the
  default `Component::get_setup_priority()` already returns
  `setup_priority::DATA`, so the override was a no-op.
