[repo] Case-insensitive address queries

[volkyeth]

Currently the repo expects Mixed-case checksum Addresses on the queries, so if we use addresses with other cases it does not find the resource.

E.g: https://repo.sourcify.dev/contracts/full_match/100/0xC4c622862a8F548997699bE24EA4bc504e5cA865/metadata.json works https://repo.sourcify.dev/contracts/full_match/100/0xc4c622862a8f548997699be24ea4bc504e5ca865/metadata.json gives a 404

The dev experience could be improved by making the query work with addresses in any kind of case. As it stands, it's often necessary to add boilerplate to convert addresses to checksum mixed-casing in the code.

Thanks a lot for the report!

@marcocastignoli wasn't it already resolved with this? #588

[marcocastignoli]

It used to work, I'll take a look at it. Thanks for the report

Related: if you pass a non-checksummed address in any of the verification tab inputs that accept addresses (Etherscan verification, contract/chain ID), it will give you a non-checksummed address "View in repository" link. I think the UI should always give a checksummed link and maybe checksum the address immediately upon entry.

Example:

The "Ethereum Mainnet" link is to a non-checksum address, and the non-checksum address is displayed in the UI.

I'm not an expert regarding nginx configuration but I tried to follow the logic and it seems like I added a useless location that I removed in this PR sourcifyeth/h5ai-nginx#1

Can someone with more experience than me regarding nginx check it?

[marcocastignoli]

@sealer3's report is fixed by this PR: #990

Locally on my machine it works... repo.staging.sourcify.dev still has the same probllem

[kuzdogan]

Leaving this aside for now as we couldn't tackle the problem successfully...

The problem currently is that the h5ai-nginx config does not match the location we are checksumming the addresses for /metadata.json or other file addresses. The location regex is not matching for some reason
