I added permanent www redirects for inbound Dashboard URLs that
currently reach the www 404 page. The project rule requires a path
segment and carries the full project suffix to Dashboard.
## To test
- In the www preview, open `/login`, `/support/new?category=billing`,
and `/account/tokens`. Each should redirect to its corresponding
`/dashboard` page and preserve the query string.
- Open `/project/<ref>` and
`/project/<ref>/database/migrations?source=docs`. Both should redirect
to the same path under `/dashboard`, preserving the suffix and query
string.
- Open bare `/project`. It should remain outside the new redirect rule.
## Linear
- fixes GROWTH-1302
