Show "Ness" instead of "harness" in the macOS app menu

The app menu's About / Hide / Quit items read "harness" because they
derive from app.name, which Electron takes from package.json's top-level
"name" — still "harness". The menu bar title is already correct since
macOS reads that from CFBundleName (build.productName).

Renaming the package or calling app.setName() is not an option: app.name
keys both the userData directory and the macOS Safe Storage keychain
item, and the keychain is case-sensitive, so either would break
secrets.enc decryption. Instead, set explicit labels from a new
APP_DISPLAY_NAME constant, and set the About panel's applicationName so
the dialog behind the About item matches too.
