O images loaded from unreliable source

[0xcadams]

The current ENS image loading comes from https://metadata.ens.domains/mainnet/avatar/, which has caused issues in the past. We should load directly from IPFS/URL (or a better cache source) and avoid reliance on this service.

Hi @0xcadams, I wanted to address the long load times for some avatars on the Explorer. Can you confirm if this was partly addressed in your commit b34f68f? Specifically, I'm referring to the changes in [name].tsx.

Yes, this was addressed, and we cache image responses heavily so this should be partially resolved.

How long is the caching window?
