feat: unified routing with Drive mode default and Add stop wedge

- Add Drive (auto) as default route mode, first in travel modes list
- Hide boundary mode selector when Drive mode is active
- Restore Add stop radial menu wedge with stops system integration
- Unify routing through single computeRoute() function in store
- Add coordinate parsing to SearchBar for direct lat/lon input
- Bridge stops system with routeStart/routeEnd for seamless UX
- Support 3+ stops with Valhalla optimization
