fix: add catch-all route and improve hash redirect handling

- Add catch-all route (*) that redirects to home for unknown paths
- Support both #/apps and #apps hash formats from HF parent
- Use history.replaceState instead of window.location.hash for cleaner
hash cleanup without potential side effects
