fix(website): bundle the PostHog init so analytics actually loads

[mmabrouk]

What

Analytics never initialized on the live site: the init script was emitted inline (via define:vars), and an inline script's import("posthog-js") is a bare module specifier the browser cannot resolve — it threw an unhandled promise rejection on every page load. Zero events reached PostHog.

Fix

Make the script a bundled Astro client script. Vite statically replaces the PUBLIC_POSTHOG_KEY / PUBLIC_NOINDEX reads in bundled client code, so the inline value handoff was never needed. The host guard (agenta.ai / www only) and DNT handling are unchanged. Verified: the built Analytics chunk contains posthog-js and pages reference it; live event delivery confirmed on agenta.ai after a direct production deploy.
