[Tests] Deduplicate power-of-two assertion message

[mrz1836]

What Changed

• Introduced a shared powerOfTwoMessage constant in power_of_two_test.go so each assertion references the same format string.

Why It Was Necessary

• Removes repeated literals that triggered a maintainability warning and keeps the assertion output consistent.

Testing Performed

• /root/.local/share/mise/installs/go/1.24.3/bin/golangci-lint run --config=.golangci.json
• go test ./...

Impact / Risk

• Low risk – this is a small refactor limited to test assertions.
