fix(redirects): serve legacy redirects in production via render.yaml

Production runs on Render (a manually-created static site), which ignores
vercel.json — so the redirects wired up in #71 never applied in prod. The live
service also had broad SPA-fallback rewrites (/sdk/*, /react/*, /smart-wallet/*,
/meta-infra/*, /recovery-flow/*) that, under Render's first-match-by-priority
routing, swallowed ~145 of the 201 legacy URLs into the app shell (-> in-app 404).

- render.yaml: Render Blueprint that adopts the existing "docs" static site.
  Generated redirects sit ABOVE the SPA-fallback rewrites so they take priority.
- redirects.config.js stays the single source of truth; folds in /magic-account
  (collapsing its stale /sdk/advanced/chain-abstraction hop).
- scripts/sync-render-redirects.mjs splices the generated block between
  sentinels, preserving the hand-maintained service def + fallbacks. Output is
  prettier-clean by construction.
- CI (redirects-in-sync) + npm scripts now target render.yaml.
- Remove the unused vercel.json and its sync script.
