tiennm99 53ee7957e7 refactor(storage): migrate to Upstash REST SDK with KEY_PREFIX
Replace node-redis with @upstash/redis REST client and route all keys through
a centralized adapter that prepends KEY_PREFIX (default 'vngeoguessr:'). The
new Upstash DB can now be safely shared with other Vercel projects without
key collisions.

- src/lib/upstash.js: new adapter with getJson/putJson/del + zAdd/zRange/
  zScore/zRank/zRevRank/zRemRangeByRank helpers; reads UPSTASH_REDIS_REST_URL
  or KV_REST_API_URL aliases
- src/lib/session.js, src/lib/leaderboard.js: use the adapter; public APIs
  unchanged so api routes stay untouched
- src/lib/redis.js: removed
- scripts/migrate-upstash.js: one-shot copy from old TCP DB to new REST DB,
  prepending the prefix; idempotent, with --dry-run flag
- docs/tech-stack.md: reflect the new SDK and prefix model
