Set pragma to solidity 0.8.24

[saucepoint]

Component

General design optimization (improving efficiency, cleanliness, or developer experience)

Describe the suggested feature and problem it solves.

With #473 replacing the custom solc in favor of 0.8.24, foundry will not default to 0.8.24 until it compiles at least once with some version hint (i.e. in foundry.toml or a file with pragma 0.8.24)

Afterwards, it should default to 0.8.24. in its current state, its annoying to have to manually nudge it

Describe the desired implementation.

• pin solc = "0.8.24" in foundry.toml
• Update any file that touches or is related to Lockers.sol. For other files, i.e. SwapMath can probably stay unchanged

Describe alternatives.
