add new schema with resolver contract to back-end config, ensure multi-attest works

[divine-comedian]

we will implement a smart contract function allowing users to issue attestations, issue multiple attestations and also collect a small fee on each attestation they make,

https://github.com/Giveth/DeVouch-contracts/blob/master/src/DevouchAttester.sol#L44

we should ensure the back-end captures attestations made in this new way and attributes them correctly in our DB.

AC

VOUCHES issued by users (with new smart contract implemented) show the correct information

• address of attestor
• project id
• attributed as vouch correctly
• date of attestation
• attestor group made as
• comments made

FLAGS issued by users (with new smart contract implemented) show the correct information

• address of attestor
• project id
• attributed as flag correctly
• date of attestation
• attestor group made as
• comments made

EDIT

• when user edits their attestation information is updated correctly
• if vouch changed to flag
• if they replaced a comment with a new one (or added one if there was no comment before)
• there is no duplicate, the previous attestation is correctly replaced with the updated one.

REVOKE/DELETE

• when user deletes their attestation it is correctly removed from project and user's attestation information in DB

We made a new schema using a resolver contract which will collect fees and can be upgraded to add more functionality later on. We need to add this to our back-end config array on SEPOLIA to start testing it:
