[EPIC]: add usage and coverage for Frictionless Airdrop (HIP-904)

[quiet-node]

Problem

HIP-904, Frictionless Airdrop, has been fully implemented in [email protected] but currently lacks Solidity usage and test coverage.

Solution

Implement Solidity usage and add test coverage to verify that all features function as expected.

5. Add example contracts and include the HRC-904 methods in the HTS contract #1160
   enhancement +1
   
6. Add tests that verify IHRC904 airdropToken targeted to an EOA are functional when called by a contract #1109
   enhancement +1
   
7. Add tests that verify IHRC904Proxy methods targeted to an EOA are functional when called by EOA #1147

Note: As of 0.56 the target of an airdrop should be an EOA. Also MN does not yet support this logic

@quiet-node or @victor-yanev let's clean up #1011 and get it in now.
May also need to do a positive handoff to another team member to handle this depending on how sprint planning goes.
Whoever picks this up should sync w @stoyanov-st for context on latest 0.57 functionality as there may be new gaps.

[Nana-EC]

@quiet-node added that we should upgrade the local node version of the repo to support this and ensure the feature flag is turned on.
