fix(foundry): resolve ABI when source file name differs from contract name

[rin-st]

Noticed by Damu here

Summary

• generateTsAbis.js looked up artifacts at out/<ContractName>.sol/<ContractName>.json, so contracts whose source file name differs from the contract name (e.g.
  OracleToken.sol containing contract ORA) were silently skipped and never appeared in deployedContracts.ts (or the debug page).
• Fall back to scanning out/*.sol/ for <ContractName>.json when the conventional path doesn't exist. Fast path unchanged when names match.

Test plan

• In a Foundry extension, rename a contract so it differs from its file name (e.g. file Foo.sol with contract Bar), deploy via a script, verify Bar appears in packages/nextjs/contracts/deployedContracts.ts and on the debug page. Example extension: Foundry support - Challenge-oracles se-2-challenges#440 . OracleToken.sol file with contract named ORA
• Regression: verify contracts where file name matches contract name still resolve (fast path).

Test commands

yarn build:dev

yarn cli -e https://github.com/scaffold-eth/se-2-challenges/tree/challenge-oracles-foundry-v2 -s foundry --dev

Thanks @rin-st!!

Working great and code looks good!

Small comment:

yarn cli -e https://github.com/scaffold-eth/se-2-challenges/tree/challenge-oracles-foundry-v2 -s foundry --dev

dev flag doesn't work with URL (makes sense).
