fix(docs): fix decorateUrl bugs in navigate callback examples

- Use `url` variable instead of hardcoded '/' in else branch (legacy/application-invitations)
- Replace `router.push` with `window.location.href` in vanilla JS examples (multi-session, clerk.mdx)
- Add missing `return` after currentTask check to prevent fall-through navigation
- Remove `window.location.href` from Expo examples where it doesn't exist in React Native
