feat(inbounds): native fallbacks on VLESS/Trojan TCP-TLS, with working child links
A VLESS or Trojan inbound on TCP with TLS or Reality can now act as a
fallback master: pick existing inbounds as children and the panel auto-
fills the SNI / ALPN / path / xver routing fields from each child's
transport, auto-builds settings.fallbacks at config-gen time, and
rewrites the child's client-share link so it advertises the master's
reachable endpoint and TLS state instead of the child's loopback listen.

Layout matches the Xray All-in-One Nginx example: master at :443 with
clients + TLS, each child on 127.0.0.1 with its own transport+clients.
Order matters (Xray walks fallbacks top-to-bottom) — reorder via the
per-row up/down arrows. Path / SNI / ALPN are exposed under a per-row
Edit toggle for the rare cases where the auto-derivation needs
overriding; otherwise just pick a child and you're done.

Backend: new InboundFallback table + FallbackService (GetByMaster /
SetByMaster / GetParentForChild / BuildFallbacksJSON); two routes
(GET / POST /panel/api/inbounds/:id/fallbacks); xray.GetXrayConfig
injects settings.fallbacks for any VLESS/Trojan TCP-TLS/Reality
inbound; GetInbounds annotates each child with FallbackParent so the
frontend can rewrite links without an extra round-trip.

Link projection covers every emission path — clients-page QR/links,
per-inbound Get URL, raw subscription, sub-JSON, sub-Clash, and the
inbounds-page link/info/QR — via a shared projectThroughFallbackMaster
on the backend and a shared projectChildThroughMaster on the frontend
that both handle the panel-tracked relationship and the legacy
unix-socket (@vless-ws) convention.

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").
