## PR-Codex overview
This PR updates the `rewrites` function in `next.config.mjs` to include
a new structure for handling URL rewrites, adding `beforeFiles` and
`afterFiles` sections, and introduces several new rewrite rules for
deprecated endpoints.

### Detailed summary
- Changed the return value of the `rewrites` function from an array to
an object.
- Added `afterFiles` section with existing rewrite rules for
`/info/token/:address`, `/info/pool/:address`, and
`/.well-known/vercel/flags`.
- Introduced `beforeFiles` section with new rewrite rules for deprecated
endpoints at `/info/v3` and its sub-paths.
