Report HTML: add 'Fix all now' button that jumps to the CTA

Mirror the website 'Fix all now' button in the skill's report-template.html (the S3-hosted report). Primary green button next to Share; clicking scrolls to the end CTA + pulses it. No link.

Done — merged in #32. Same button in the S3 report template; 17/17 tests pass, verified in browser.
