Fix CSP violations from Cloudflare Radar scan

Two duplicate <meta> CSP tags in index.html conflicted with the
_headers HTTP header, and browsers enforce the intersection of all
active policies. That blocked the profile photo, the inline nav-
highlight script, and the Cloudflare Insights beacon.

Consolidate to a single CSP in _headers, allow the actual external
resources the page needs (ki5bhv.com image, cloudflareinsights.com
beacon), and move the inline script/onerror handler into js/main.js
so script-src no longer needs 'unsafe-inline'.
