Port popup to React; fix backend port colliding with Vite dev server

Browse Source 
Popup is now a real React app (App.tsx/main.tsx via createRoot),
wired through @wxt-dev/module-react. tsconfig.json needed an explicit
jsx: "react-jsx" -- WXT's generated .wxt/tsconfig.json doesn't set
it, so tsc --noEmit failed on JSX syntax even though the Vite build
itself was fine.

Root cause of the actually-reported bug (blank popup, predating the
React port too): the backend defaulted to port 3000, the same port
WXT's dev server uses for this extension. With both running, the
popup's script tags pointed at the Vite dev server but the backend
answered instead, so main.tsx never loaded -- "View Page Source"
showed raw unbundled dev-mode HTML pointing at localhost:3000.
Backend now binds :8080 (see backend commit), and
BACKEND_HTTP_URL/BACKEND_WS_URL + host_permissions here follow it.

## Backend connection (implemented)
- `src/shared/config.ts` — `BACKEND_HTTP_URL`/`BACKEND_WS_URL`, currently hardcoded to `localhost:3000` (dev only; `host_permissions` in `wxt.config.ts` must stay in sync with whatever host is configured here).
- `src/shared/config.ts` — `BACKEND_HTTP_URL`/`BACKEND_WS_URL`, currently hardcoded to `localhost:8080` (dev only; `host_permissions` in `wxt.config.ts` must stay in sync with whatever host is configured here). Deliberately not `:3000` — that's this extension's own Vite dev server port (`npm run dev`), and running the backend on the same port breaks the dev popup silently: its script tags point at Vite, but the backend answers instead, so nothing ever renders. If you see a blank popup with `http://localhost:3000/...` script tags in "View Page Source" that 404 or return something unexpected, this port collision is the first thing to check.
- `src/background/identity.ts` — **stub wallet**: a locally-generated ed25519 keypair (via `tweetnacl`), persisted in `browser.storage.local`, used as a stand-in for a real Solana wallet signature. This is deliberately temporary — real wallet integration means bridging into the page's injected `window.solana` provider on axiom.trade (content script + page-context script), which hasn't been built yet. `getIdentity()`/`sign()` is the seam that swap plugs into.
- `src/background/backend-client.ts` — the REST auth flow (`POST /auth/nonce` → sign → `POST /auth/verify` → session token), persisted via `getSessionToken()`.
- `src/background/ws-client.ts` — the WS client described above: connects to `/ws?token=...`, reconnects with the protocol's suggested backoff, force-refreshes the session token on `4001`/`auth_expired` before retrying.
