Upgrade to go 1.24 and fix lint errors (#681)

* Remove deprecated linters

* Use new range in benchmark loops

* Add timestamp overflow check for validator registrations

* Define gasLimit as a uint64

* Replace "golang.org/x/exp/slices" with stdlib "slices"

* Use require.JSONEq

* Add a bunch of //nolint:gosec comments for timestamp conversions

* Disable deprecated tenv linter

* Define new errTimestampOverflow var

* Bump golang to v1.24

* Run go mod tidy

* Replace context.Background() with t.Context() in tests
