Serve security headers via static-web-server, drop Cloudflare deploy path

Production (Dokploy/Docker) was sending no security headers at all -
static/_headers and wrangler.toml were Cloudflare Pages/Workers
config that static-web-server never reads. Added sws.toml with the
same CSP/security headers and the two redirects from _redirects,
wired into the Dockerfile. Removed wrangler.toml, static/_headers,
static/_redirects, the wrangler devDependency/deploy script, and
related .gitignore/.dockerignore entries since Cloudflare deploy is
no longer used.

Also fixed a console error in theme.js where the Utterances
postMessage call could fire before the comments iframe navigated to
utteranc.es.

+Deployment is self-hosted via Dokploy: `Dockerfile` builds the site with Zola and serves `public/` with `static-web-server`, configured by `sws.toml` (security headers, redirects) at the image's working directory root.
