[codex] homepage refresh and map

[kpoxo6op]

What changed

This refreshes the homepage into a clearer landing page for the project and adds a map-driven browsing experience based on the post coordinates.

Highlights

• rebuilds the homepage hero and story grid
• adds a Leaflet map with marker clustering and popup previews
• syncs map viewport state into the URL without reloading the map on drag
• adds post location coordinates to the before/after JSON entries and extends the post loader/types
• adds an RSS feed route at /feed.xml
• adds a visible footer version string based on the app version and deployed Vercel deployment id
• updates the mobile homepage heading so New Zealand and Then and Now split onto separate lines on small screens

Why

The old homepage did not explain the site clearly enough and did not surface the geographic structure of the stories. The map and simplified layout make the archive easier to browse and verify.

Validation

• corepack pnpm lint
• corepack pnpm typecheck
• corepack pnpm build
• corepack pnpm test:e2e

Notes

• The repo still emits existing Failed to fetch posts noise during Playwright webserver startup, but the full e2e suite passes.
• The current preview deploy includes the exact footer version string for the deployed build.
