feat: add Antseed AI Credits analytics dashboard

[thalescb]

What

Self-contained browser dashboard for the GoodDollar x AntSeed AI Credits integration. Fetches daily analytics from the Antseed Worker endpoint and visualizes G$ deposit volume, AI credit usage, and wallet activity.

Live preview (once merged): https://gooddollar.github.io/data-team/antseed-analytics/dashboard/

What it shows

• Hero scorecards: Total G$ spent (one-time + streamed), AI credits used (USD), current flow rate (G$/day)
• 3 charts: G$ volume stacked area (deposits + streamed), AI credits/day bar, unique wallets/day line (G$ buyers vs credit users)
• Paginated daily summary table (10 rows/page, sorted newest first)
• System info with contract addresses linked to block explorers
• Live/Demo toggle to preview the layout with sample data while the Worker endpoint is pending

Data source

Fetches from \GET /v1/analytics?days=365\ on the Antseed Worker. The endpoint serves pre-aggregated daily data from Cloudflare KV.

Status: The Worker endpoint is not yet deployed -- waiting on antseed-integration PR #19 to merge. The dashboard shows a graceful fallback with demo data until then. Once the endpoint is live, it works immediately with no code changes.

Metrics coverage

All metrics requested by Hadar in issue #13 are covered:

Requested	Status
Daily G$ one-time deposits	Covered
Daily G$ streamed	Covered
Current total flow rate	Covered
Daily AI credits used	Covered
Daily unique wallets (G$ buyers)	Covered
Daily unique wallets (credit users)	Covered
Global aggregated sums	Covered

Not in scope (not available in the Worker API response -- would need separate queries or API additions):

• GoodID verification rate
• New vs returning depositors breakdown
• Base operator USDC balance / runway

Files

File	Purpose
\projects/antseed-analytics/dashboard/index.html\	HTML structure + CSS
\projects/antseed-analytics/dashboard/app.js\	All application logic (API fetch, BigInt conversions, Chart.js rendering, table pagination, demo data generator)
\README.md\	Updated structure tree + active projects table
\docs/dashboards.md\	Added dashboard entry

Tech

• Chart.js 4.4.7 from CDN
• No build step -- opens as a local file or deploys to GitHub Pages
• Auto-refreshes every 5 minutes
• Same dark-mode design pattern as the Superfluid campaign dashboard

Dashboard is now deployed to GitHub Pages. Live URL:

Currently shows demo data (toggle between Live Data and Demo Preview at the top). Once antseed-integration PR #19 merges and the Worker endpoint goes live, real data loads automatically.
