fix: ts configs and tests

[kalote]

What does this PR introduce?

The typescript configuration was not including the tests/ folder and has some inconsistencies (exclude is useless when there is an include for example).
By fixing it, a lot of error on the tests emerged. They have been fixed too.

FYI,

• the storageLayout instructions is not working fine (the type is not generated even though it has been set in the hardhat.config.ts) => open issue on hardhat repo The CompilerOutputContract type doesn't include fields for optional outputs NomicFoundation/hardhat#4425
• in order to work around this, I added the ts-ignore line
• the ts-ignore line is not well appreciated by eslint, so I had to also ignore the linter from yelling at me using @eslint-disable-next-line
