feat: add Usdfc to wagmi config

[pali101]

This PR adds the USDFC contract definition to the wagmi.config.ts file, allowing the CLI to generate typed hooks for interacting with the token. This is a necessary step to integrate features that use USDFC extensions like ERC-2612 and ERC-3009.

This change is dependent on the ABI being available from the filecoin-services repository.

Prerequisite: FilOzone/filecoin-services#263 must be merged first.

Closes #244

we are moving away from getting all the abis from that repo.

is filfox api compatible with etherscan? https://wagmi.sh/cli/api/plugins/etherscan#tryfetchproxyimplementation

if not can we hardcode impl address and use https://wagmi.sh/cli/api/plugins/blockExplorer

or just do the 2 step in fetch

@hugomrdias I've implemented a custom fetcher script that pulls the latest ABIs directly from the Filfox API, removing the dependency on the filecoin-services repo.
The script handles proxy contracts by first finding the implementation address and then fetching its ABI, as you suggested.
This means we can now simply add contract definitions to the wagmi.config.ts, and the script will automatically fetch the correct, up-to-date ABI. I've pushed the changes. Let me know what you think.
