Several cross-cutting fixes and refactors:
- API routing: Consolidated multiple org policy PUT endpoints into a single parameterized route (/api/org/{id}/policy/{category}) to simplify handlers (api/server.go).
- Relay/LAN handling: Prefer server LAN IP for LAN relay addresses (with proper port detection from configured relay), added strconv import and fallback to configured relay when LAN IP unknown; improves reliability with NAT hairpin issues (signal/handler.go).
- Web security: Allow inline event handlers (scriptSrcAttr: 'unsafe-inline') while still requiring nonced <script> tags for scripts used by admin pages (web-nodejs/middleware/security.js).
- CSRF: Include x-csrf-token header when POSTing language fix requests from the UI (web-nodejs/public/js/languages.js).
- Admin roles: Broaden admin checks to accept multiple admin role names via ADMIN_ROLES and update requireAdmin and RustDesk payload is_admin logic (web-nodejs/routes/rustdesk-api.routes.js).
- Admin credentials & startup resilience: authService now searches additional candidate dirs (config.dataDir, extra Windows/RustDesk paths, /app/data in Docker), skips empty candidates, and increases retries/delays when waiting for .admin_credentials (web-nodejs/services/authService.js).
- Chat API paths: Updated chat-related API calls to use /chat/* (instead of /api/chat/*) across persistence, history, contacts, groups, read and other operations (web-nodejs/services/chatRelay.js).
These changes improve compatibility (LAN relay, admin detection), robustness (longer retries, Docker/Windows path checks), and frontend behavior (CSRF token, inline handlers, updated chat endpoints).
Add unit tests and test helpers (5 suites, 41 tests) and test npm scripts; introduce deviceStatusPush service and WS real-time device status push integration. Fix chatRelay to acknowledge connections (send `welcome`), and apply multiple web remote/rdclient fixes (video ack/timing, keyframe refresh, SourceBuffer trimming, input focus handling) to improve FPS and control. Add new server route file (system.routes.js), new device-status service, update server.js and package.json, and modify various frontend CSS/JS/views. Update English and Polish locale files with many new widget/i18n keys and remove the Russian locale file (ru.json). Also include assorted UI/desktop-widget dashboard tweaks and documentation status updates in .github/copilot-instructions.md.
Introduce persisted chat features and a BetterDesk desktop management WebSocket channel. Adds new REST chat handlers (history, send, read, unread, contacts, groups), bd-mgmt WebSocket and management REST endpoints, and routes in the HTTP server. Extend Database interface and models (ChatMessage, ChatGroup, ChatContact) and implement schema migrations + CRUD for PostgreSQL and SQLite. Adjust auth middleware to allow /ws/bd-mgmt/* and relax server WriteTimeout / increase IdleTimeout to accommodate long-lived WS connections. Also add a 3.0 roadmap document and minor frontend/localization/service updates related to chat and relay.
Add a new betterdesk-server Go codebase (server, api, auth, db, relay, signal, metrics, audit, ratelimit, proto, tools, tests) and related deployment/migration scripts. Add a comprehensive SECURITY_AUDIT_2026-03-01 report and .gitattributes; update copilot-instructions (ALL-IN-ONE v2.4.0), README, VERSION, Dockerfiles, scripts, docker-compose and entrypoint. Large updates to web-nodejs (translations, routes, services, frontend assets and middleware) and numerous new utilities; remove legacy Flask web files and archive hbbs-patch-v2 artifacts. Prepares repository for PostgreSQL support, DB migration tooling and the new Go server as the production backend.
