Check if authorPublicKey in KeyBoxes matches the one in the chain

[nikgraf]

Here we directly use the authorPublicKey, but it should be matched:

      await transaction.spaceKeyBox.createMany({
        data: keyBoxes.map((keyBox) => ({
          id: `${keyBox.id}-${inviteeAccountId}`,
          nonce: keyBox.nonce,
          ciphertext: keyBox.ciphertext,
          accountId: inviteeAccountId,
          authorPublicKey: keyBox.authorPublicKey,
          spaceKeyId: keyBox.id,
        })),
      });
