[Type] The field type returned by AnnotatedMoveValueView is inconsistent with the actual type

[baichuan3]

The current implementation of AnnotatedMoveValueView may be flawed. Coin balance defines the U256 type, but the type obtained from AnnotatedMoveValueView is U64(StrView(10000), and the expected type is U256(StrView(10000).

Guess AnnotatedMoveValueView May return U128(StrView(value) type if the coin value big enough.

The Case

value: {Identifier("value"): U64(StrView(10000))} })

relative of https://github.com/rooch-network/rooch/pull/760 https://github.com/rooch-network/rooch/blob/467707e7f294d23277ac8aa7fd026fd0aea7354f/crates/rooch-rpc-api/src/jsonrpc_types/rooch_types.rs#L193-L221

Because the U64, U128, and U256 in AnnotatedMoveValueView all represent via StrView.

And the AnnotatedMoveValueView is #[serde(untagged)], so we will lose the type when serializing to JSON.
