feat(scraper): add RWEB best-practices waves 1 and 2

[vvatelot]

Summary

• Enrich HAR parsing with HTTP version, cache headers, content-encoding, and cookie header size
• Expand the default best-practices set from 4 to 14 automated checks (waves 1 and 2), aligned with GreenIT-Analysis and RWEB
• Add datacenter rule category and register the best_practices brick in the monorepo

New rules

• Wave 1: RWEB_0032 fonts, RWEB_0035 stylesheets, RWEB_0059 social buttons, RWEB_0099 GIFs, HTTP errors
• Wave 2: RWEB_0075 cache headers, RWEB_0076 compression, RWEB_0081 cookie-free static domain, RWEB_0083 HTTP/2, RWEB_0112 redirects

Test plan

• uv run pytest test/components/ecoindex/best_practices/ -q
• Run an analysis with include_best_practices: true and confirm GET /v1/ecoindexes/{id}/best-practices returns the new rules
• Spot-check fail/warn/ok statuses against a page with known HTTP/1, redirects, or social widgets
