Use the new feature of Go 1.24, fix linter warnings. This change was produced by: - running golangci-lint run --fix - sed 's/context.Background/t.Context/' -i `git grep -l context.Background | grep test.go` - manually fixing broken tests - itest, lntest: use ht.Context() where ht or hn is available - in HarnessNode.Stop() we keep using context.Background(), because it is called from a cleanup handler in which t.Context() is canceled already.
