MAESTRO: Add /web/* route namespace for web interface

Created dedicated web interface route namespace in WebServer class:
- /web - Root endpoint returning available interfaces info
- /web/desktop - Desktop web interface entry point (placeholder)
- /web/desktop/* - Wildcard for client-side routing
- /web/mobile - Mobile web interface entry point (placeholder)
- /web/mobile/* - Wildcard for client-side routing
- /web/api - Web API namespace root with endpoint discovery

This establishes the foundation for the new web interface that will
provide both desktop (collaborative) and mobile (remote control)
access to Maestro sessions.
