1. In dev mode, discover themes from source files in
`web_src/css/themes/` instead of AssetFS. In prod, use AssetFS only.
Extract shared `collectThemeFiles` helper to deduplicate theme file
handling.
2. Implement `fs.ReadDirFS` on `LayeredFS` to support theme file
discovery.
3. `IsViteDevMode` now performs an HTTP health check against the vite
dev server instead of only checking the port file exists. Result is
cached with a 1-second TTL.
4. Refactor theme caching from mutex to atomic pointer with time-based
invalidation, allowing themes to refresh when vite dev mode state
changes.
5. Move `ViteDevMiddleware` into `ProtocolMiddlewares` so it applies to
both install and web routes.
6. Show a `ViteDevMode` label in the page footer when vite dev server is
active.
7. Add `/__vite_dev_server_check` endpoint to vite dev server for the
health check.
8. Ensure `.vite` directory exists before writing the dev-port file.
9. Minor CSS fixes: footer gap, navbar mobile alignment.

Replace webpack with Vite 8 as the frontend bundler. Frontend build is
around 3-4 times faster than before. Will work on all platforms
including riscv64 (via wasm).
`iife.js` is a classic render-blocking script in `<head>` (handles web
components/early DOM setup). `index.js` is loaded as a `type="module"`
script in the footer. All other JS chunks are also module scripts
(supported in all browsers since 2018).
Entry filenames are content-hashed (e.g. `index.C6Z2MRVQ.js`) and
resolved at runtime via the Vite manifest, eliminating the `?v=` cache
busting (which was unreliable in some scenarios like vscode dev build).

When running `make watch`, the backend may start before webpack finishes
building CSS theme files. Since themes were loaded once via sync.Once,
they would never reload, breaking the theme selector and showing a
persistent error on the admin page.
In dev mode, themes are now reloaded from disk on each access so they
become available as soon as webpack finishes. Production behavior is
unchanged where themes are loaded once and cached via sync.Once.

Initial support for #25680
This PR only adds some simple styles from GitHub, it is big enough and
it focuses on adding the necessary framework-level supports. More styles
could be fine-tuned later.
