Migrate From ContractKit to Viem

[aaronmgdr]

Description

Rather than use ContractKit use viem as the rpc caller / contracts library.

Changes

• WalletSigner now takes a sign191 function instead of a contractKit instance. this makes it easy to use with whatever library you like such as viem client.signMessage or ethers.signMessage as long as they support eip191.

• Many places that were expecting an address but typed as a regular string are now typed as 0x{string} aka Address

• almost everywhere kit has been replaced with client and in some cases walletClient

• @celo/phone-number-privacy-common/lib/contracts contract instances used internally (viem getContract + abi + address) getAccountsContract, getCUSDContract, getOdisPaymentsContract,

• ContractKit is still needed for the @celo/identity/lib/offchain functions however these are not used in social connect as such ck is now a peer dependencies and marked as optional. Pottentially these offchain functions can be either deprecated or moved to a different codebase.

Tested

Needs someone who understand the system really well to really test it out.

TODO

• need to re mock the getDataEncryptionKey method in the authentication.test in common package. one was done but the rest still need it and each seems to require different implementatation

• try to replace contractkit with @celo/[email protected]

dont merge until we get this deployed to staging.
