Redirect rules not working for renamed miniapps paths

## Problem
Legacy URLs from the miniapps path reorganization (commit 7abc5c5) don't redirect properly, causing 404s for existing bookmarks and external links.

**Expected:** `docs.base.org/base-app/build-with-minikit/quickstart` → `docs.base.org/base-app/miniapps/quickstart`
**Actual:** All legacy URLs redirect to `docs.base.org/get-started/base`

## Impact
- Broken user experience for existing bookmarks
- SEO degradation from 404s
- Poor developer experience
