feat(web): add @reactuses/core and reorganize atoms

- Install @reactuses/core for React hooks (13.2 KB gzip, React 19 support)
- Create theme-atoms.ts (separate themeAtom from user-atoms)
- Create location-atoms.ts (useLocation from jotai-location)
- Update user-atoms.ts (remove themeAtom, add debugLabels)
