style: strictly enforce semicolon termination + curly braces on all JS statements

- lib.js, test/lib.test.js, and all executable JS in TailscaleWidget.qml (onExited handlers, custom methods, onClicked blocks) now terminate every statement with ;
- All if/for/while blocks use {} even for single statements (per repo code style rules)
- No behavior change; all tests continue to pass
- This was the missing follow-up to the previous refactor (the changes existed in the working tree but were never committed on the feature branch)
