Several redirects point to /apps/introduction/overview which has no page

A number of redirects in docs.json point to /apps/introduction/overview but there is no page at that path (docs/apps/introduction/ does not exist). So all of them land on a 404.

The sources are mostly old MiniKit pages plus a couple of others:

- /onchainkit/latest/components/minikit/overview
- /onchainkit/latest/components/minikit/provider-and-initialization
- /onchainkit/latest/components/minikit/hooks/useMiniKit
- /onchainkit/latest/components/minikit/hooks/useOpenUrl
- /onchainkit/latest/components/minikit/hooks/useClose
- /onchainkit/latest/components/minikit/hooks/usePrimaryButton
- /onchainkit/latest/components/minikit/hooks/useViewProfile
- /onchainkit/latest/components/minikit/hooks/useComposeCast
- /onchainkit/latest/components/minikit/hooks/useViewCast
- /onchainkit/latest/components/minikit/hooks/useAuthenticate
- /onchainkit/latest/components/minikit/hooks/useAddFrame
- /onchainkit/latest/components/minikit/hooks/useNotification
- /cookbook/base-app-coins

There is also a content link to the same dead path in base-account/guides/verify-social-accounts.mdx (the "Apps overview" link).

I did not send a fix because the right target is not obvious. /apps is a build tutorial rather than an overview. These might belong on /apps or /apps/guides/migrate-to-standard-web-app but that is a call for the team. Happy to open a PR once you confirm where they should go.
