chore(frontend): TypeScript 6.0.3 + lucide-react 1.23.0

- typescript 5.9.3 -> 6.0.3: no code changes needed (tsconfig already
strict; typecheck clean in next build).
- lucide-react 0.511 -> 1.23: all imported icons unchanged.
- ESLint stays on 9.x (9.39.4): eslint-config-next's bundled
eslint-plugin-react (7.37.5, latest) crashes on ESLint 10
(removed context.getFilename API) and none of its plugins declare
eslint 10 support yet. Revisit when Next ships an ESLint-10-ready
config, likely 16.3.

Verified: npm run lint + npm run build clean.
