feat(inbounds): add Port-with-Fallback inbound type 
Adds a new "portfallback" protocol that emits as a VLESS-TLS inbound
under the hood but is paired with a sidecar table of child inbounds.
Panel auto-builds settings.fallbacks at Xray-config-gen time from the
sidecar — each child's listen+port becomes the fallback dest, with
SNI/ALPN/path/xver match criteria pulled from the row. No more typing
loopback ports by hand or keeping settings.fallbacks in sync.

Backend: new FallbackService (Get/SetChildren, BuildFallbacksJSON);
two new routes (GET/POST /panel/api/inbounds/:id/fallbackChildren);
xray.GetXrayConfig injects fallbacks for PortFallback inbounds; the
inbound model emits protocol="vless" so Xray accepts the config.

Frontend: PORTFALLBACK joins the protocol dropdown; selecting it
shows the standard VLESS controls plus a Fallback Children table
(inbound picker + per-row SNI/ALPN/path/xver). Children are loaded
on edit and replaced atomically on save.

README.md

3x-ui frontend

Vue 3 + Ant Design Vue 4 + Vite. Multi-page app — one HTML entry per panel route — built into ../web/dist/ and embedded into the Go binary via embed.FS.

Dev

npm install
npm run dev

Vite serves on http://localhost:5173/. API calls and /panel/* routes proxy to the Go panel at http://localhost:2053/, so start the Go panel first (go run main.go) and then Vite.

The proxy auto-rewrites /panel, /panel/settings, /panel/inbounds, /panel/xray to the matching Vite-served HTML in dev mode (see MIGRATED_ROUTES in vite.config.js), so the sidebar's production-style links work without round-tripping through Go.

Production build

npm run build

Outputs to ../web/dist/ (HTML at the root, hashed JS/CSS under assets/). The Go binary embeds this directory at compile time and web/controller/dist.go serves the per-page HTML.

Lint

npm run lint

ESLint 10 with eslint.config.js (flat config) — vue3-recommended plus a few rule overrides for the project's formatting style.

Adding a new page

  1. Add frontend/<page>.html referencing /src/entries/<page>.js.
  2. Add src/entries/<page>.js that imports the page component and mounts it.
  3. Add the page component under src/pages/<page>/.
  4. Register the entry in rollupOptions.input in vite.config.js.
  5. If the page is reachable from the sidebar at /panel/<route>, add it to MIGRATED_ROUTES so the dev proxy serves the Vite HTML.
  6. Wire the Go controller to serveDistPage(c, "<page>.html").
