Adjust lombok annotations to reduce build warnings

This change fixes the underlying problems behind five compiler warnings:
"Generating equals/hashCode implementation but without a call to superclass".

Some core classes use @Value and @Data annotations where not necessary, for
example, where equals, hashCode, and toString are implemented by the developer,
and where final class and field modifiers are defined by the developer.

From lombok classes and documents for the shortcut annotations
	@Value https://projectlombok.org/features/Value and
	@Data  https://projectlombok.org/features/Data,
we find some implicit annotations applied by these shortcuts are not needed.
Adjustments are described below.

- Tx Replace @Value with @Getter.

- TxOutput  Replace @Data with @Getter and @Setter.

- ChangeParamProposal  Replace @Value with @Getter.

- GetInventoryRequest, GetInventoryResponse
  An @EqualsAndHashCode(callSuper = false) is added to supress build
  warnings.
