[AAASM-3552] 📈 (docs): Wire GA4 analytics into the mkdocs site

[Chisanan232]

Description

Wires Google Analytics 4 into the Python SDK mkdocs-material docs site using Material's native analytics integration, plus the native GDPR cookie-consent so analytics cookies are gated behind explicit opt-in.

• Adds extra.analytics (provider google, Measurement ID G-L8JTJDG8G7) under the existing extra: block. The Measurement ID is a public client-side identifier embedded in the rendered HTML — it is not a secret.
• Adds extra.consent (Cookie consent banner with accept / reject / manage actions and an analytics cookie group, checked: false by default).

Claude Code — review result

✅ CI green — Analyze (python), CodeQL, Build documentation all pass. No fails to ignore.

Scope vs AAASM-3552 (python-sdk site) — covered. Wires GA4 G-L8JTJDG8G7 via mkdocs-material's native extra.analytics (provider google), plus the native extra.consent cookie banner (accept/reject/manage; analytics cookie checked: false). Two small commits. Verified mkdocs build --strict is clean and the gtag id is emitted across all built pages. The Measurement ID is public (correctly committed, not a secret); anonymize_ip semantics handled by mkdocs-material.

Ready for approval + merge. This site is the most complete of the five — it has the native consent UI built in.
