refactor: simplify Puppeteer cache cleanup to match browser cache pattern

- Replace 48-line custom function with one-line safe_clean call
- Remove unnecessary interactive confirmation (consistent with other browser caches)
- Simplify tests to verify Puppeteer cache is in clean_browsers output
- Net: -93 lines of code for same functionality
