fix: disable prerender to fix Docker build failure

- Disable TanStack Start prerender that fails in Docker due to fetch errors
- Add fallback to copy _shell.html to index.html when prerender is disabled
- Remove unused imports and variables from vite.config.ts
- Simplify build script and remove error-masking "; true"

Closes #1
