Update NPM dependencies.

Use the actual 1.0.0 (deployed on Polygon) contracts for XayaAccounts
and switch to @truffle/contract instead of the deprecated truffle-contract.
Both changes together required some tweaks in the other parts of the code,
such as deploying also NftMetadata on the Ganache environment.
