HBAR decimal places

The decimal precision of HBAR varies across the different Hedera APIs, with HAPI, JSON RPC Relay, and Hedera Smart Contract Service (EVM) returning 8 decimal places, while JSON RPC Relay msg.value returns 18 decimal places.

Note: The JSON RPC Relay msg.value uses 18 decimals when it returns HBAR. As a result, the gasPrice also uses 18 decimal places since it is only utilized from the JSON RPC Relay.
