- Move entry HTML files: frontend/*.html -> frontend/html/*.html
- Move per-page bootstrap modules: src/{index,login,settings,inbounds,xray,subpage}.js -> src/entries/
- Update vite.config rollup inputs and dev-mode MIGRATED_ROUTES to /html/<page>.html
- Build output now lands at web/dist/html/<page>.html
- serveDistPage and subController updated to read from dist/html/
Cleans up the flat frontend/ root which previously interleaved 6 HTML
files with package.json, README, src/, etc. The src/ root similarly
gets rid of 6 entry .js files mixed in alongside api/, components/,
models/, etc.
