Improve Amount usage in api

[modship]

First

• merge https://github.com/massalabs/massa-web3/blob/c87fa592dd86a30099e061c9c1aacb7a4a5fba50/packages/massa-web3/open_rpc/massa.api.json (public api part is up to date)

And then we should also :

• Update massa Amount serializer/deserializer str to accept string in nMAS and u64 nMAS (check if is decimal or no)
• update the openrpc api spec and create Amount wrapper which is oneOf [ string, number]

[modship]

Some modifications should be done, we can't safely accept Massa and nanoMassa in from str.

So, now the number provided is in nanoMassa not in Massa and we return errors when a decimal is provided

@AurelienFT can u validate if this test verify all case

#[test]
fn test_amount() {
    // decimal now return error
    assert!(Amount::from_str("15463.123").is_err());
    assert!(Amount::from_str("100.0").is_err());

    // from str now uses nanoMassa
    let amount = Amount::from_str("100").unwrap(); // nanoMassa

    // print no longer display massa unit as decimal
    // print display nanoMassa
    println!("{}", amount); // Should print 100 (nanoMassa)

    // to_raw return nanoMassa as u64 like before
    assert_eq!(amount.to_raw(), 100);
    // to_string return nanoMassa as string
    assert_eq!(amount.to_string(), "100".to_string());

    let serialized_serde = serde_json::to_string(&amount).unwrap();
    assert_eq!(serialized_serde, "100".to_string());

    // serde from_str
    let deserialized_serde: Amount = serde_json::from_str(&serialized_serde).unwrap();
    // amount from_str
    let deserialized_amount: Amount = Amount::from_str(&serialized_serde).unwrap();

    assert_eq!(deserialized_serde.to_string(), "100");
    assert_eq!(deserialized_serde.to_raw(), 100);

    assert_eq!(deserialized_amount.to_string(), "100");
    assert_eq!(deserialized_amount.to_raw(), 100);
    assert_eq!(deserialized_serde, deserialized_amount);
}

@modship sorry for the late reply the test seems very effective.

[modship]

impact in config files :

• config.toml
  • minimal_fees should be update from 0.01 to 10000000
• initial_ledger.json
  • balance should be update from ex "1000" string massa to 1000000000000 nanoMassa (has u64)

Also interface_impl.rs :

• native_amount_from_str_wasmv1
• native_amount_to_string_wasmv1

massa-client :

• read_only_execute_smart_contract
  • fee is now nanoMassa instead of Massa
• read_only_call
  • coins && fee in nanoMassa instead of Massa
• wallet_info
  • display balance in nanoMassa
  • deferred_credits in nanoMassa

Api :

• JSONRpc
  • get_status minimal_fee in nanoMassa
  • get_addresses
    • final_balance , candidate_balance, deferred_credits → nanoMassa
