Remove admin panel: strip admin startup, dependencies, and docs; keep minimal placeholder file

README.md

@@ -7,28 +7,24 @@ What I added in this commit:
 - Protocol stub (src/protocol.js) — where Rec Room / Photon packet parsing should be implemented
 - Auth helpers (src/auth.js) for Steam/RecNet token verification (placeholders that call configured endpoints)
 - SQLite persistence (src/storage.js)
-- Admin console (src/admin.js) with basic auth and endpoints to list connections and broadcast messages
 - Logger and test client
 - package.json with dependencies
 
 Environment variables (set in .env):
 - PORT (default 5055) — WebSocket server port
-- ADMIN_PORT (default 5056) — Admin HTTP server port
 - LOG_LEVEL — winston log level (info/debug/...)
 - STEAM_WEB_API_KEY — Steam Web API key (if you plan to use Steam verification)
 - RECNET_VERIFY_URL — RecNet verification endpoint to POST { token }
 - SQLITE_FILE — path for the SQLite DB file (default ./helium.db)
-- ADMIN_USER / ADMIN_PASS — optional Basic auth for admin console
 
 How to run:
 1. Copy `.env.example` to `.env` and fill in the variables you need.
 2. npm install
 3. npm start
-4. Admin console: http://localhost:5056 (use basic auth if ADMIN_USER/ADMIN_PASS set)
 
 Notes about Photon & Rec Room:
 - The client uses Photon; this skeleton provides a WebSocket entry point you can use for reverse engineering and testing. Photon traffic is binary and has its own framing — you'll need to implement Photon protocol handling inside src/protocol.js (or add a UDP/TCP transport if Photon expects that).
-- You said you can replace Photon keys and localhost yourself — good. Put the Photon server host/port to point to this process and replace any required AppId/AppVersion in the client.
+- You said you can replace Photon keys & localhost yourself — point the client at this process and replace any required AppId/AppVersion in the client.
 
 Next steps I can take after you confirm:
 - Implement Photon framing and basic handshake to accept a 2023 Rec Room client (requires packet captures or protocol docs).
