Fix CI failures from the CLI11 refactor

Three regressions surfaced by CI (develop is green):

- Linux build: std::int64_t (== long on LP64) vs juce::int64 (== long long)
  made expectEquals template deduction fail. Cast the settings int64 fields
  to juce::int64 in CommandLineTests. (macOS compiled because there the two
  types are identical.)
- "Pluginval as Dependency" Verify: verify_pluginval runs
  `pluginval --help | grep "JUCE v<version>"`. CLI11's auto help didn't print
  the JUCE version; add it to the help footer.
- Windows --run-tests exit 127: runUnitTests() called the [[noreturn]]
  juce::ConsoleApplication::fail(), which throws; outside a ConsoleApplication
  command handler that throw was uncaught -> std::terminate. Set the
  application return value directly instead.
