fix: E2E pipeline — vite preview instead of nginx, ts build fixes

Three problems caused E2E browser tests to fail in Forgejo CI:

1. TypeScript build errors in  (frontend.e2e.Dockerfile):
   -  used parameter property  which violates
     . Replaced with explicit property declaration.
   -  included  in type-checking, causing
     mock Response type mismatches. Added .
   -  mock Order was missing  field.

2. Nginx SSL crash:
   -  copied production
     which references SSL certs that don't exist in the e2e image.
   - Replaced nginx entirely with  (simpler, no SSL needed).
   - Added  to  so  routes to backend.

3. Docker context hygiene:
   -  excludes  so test files don't
     bloat the build context or trigger type errors in the container.

All other files untouched.
