fix: resolve type-check and unit test failures for CI

- vite.renderer.config: remove deprecated babel option from @vitejs/plugin-react v6
- server/main.ts: cast fastify instance to fix version mismatch TS error
- proxy-tool-streaming.test: pass 3 args to ProxyService constructor (added TokenUsageService mock)
- input.test: update expected classes (rounded-lg, bg-muted/50)
- StatCard.test: update selectors and accent classes to match component (rounded-lg, /8 opacity, bg-white/[0.04])
- paths.test: relax executable path assertion for CI environments
- cloud-repo.test: add fs mock to prevent EACCES on /mock/db
- cloudHandler-sync.test: add traffic-logger mock to prevent EACCES on /mock/
