feat(ga4): Google Analytics integration with delta reconciliation - #810

🟢 Confidence 5/5 · safe to merge
Both changed files only render GA status, and every symbol they call (Badge variants, countLabel, formatRelativeTime, catalogEntry) was read and matches.
_{quality 100/100 · no findings · tests not needed · risk low}

The two files touched since the last review now use real badge tones and countLabel, closing both open findings without adding defects. Safe to merge.

• google-analytics-integration-card.tsx chips use warn/secondary badge variants
• Catalog GA status returns warn/ok and countLabel for property counts
• Catalog entry added with no docsUrl until the docs page exists
• GA overview derives health from revoked, erroring and unstarted properties

Fixed since the last review

• ✅ F7 · Badge variant="warning" is not a defined variant, so the chip renders untinted
• ✅ F8 · Catalog status returns warning and success, neither a CardStatus/Badge variant
