revert(frontend): keep entry HTML files at frontend/ root

The earlier move to frontend/html/ made dev-mode URLs ugly
(http://localhost:5173/html/index.html instead of plain /). The folder
didn't add real value — it just hid 6 files behind a non-conventional
layout. Reverting that piece while keeping src/entries/ (which is a
genuine separation between page bootstrap and the rest of src/).

- HTML files back at frontend/<page>.html
- Vite rollupOptions.input + MIGRATED_ROUTES restored to flat paths
- Build output is web/dist/<page>.html again
- web/controller/dist.go and sub/subController.go read from dist/<name>
