NPM Improvements

I would like to suggest a few enhancements that could improve the overall functionality and bring NPM closer to current standards:

1. HTTP/3 Support (QUIC)
   Enabling HTTP/3 would significantly improve performance for clients using modern browsers, especially in environments with unstable or high-latency networks.
   2.Support for "Domain/IP + optional path" when creating a Proxy Host
   Inspired by NPMplus, adding the ability to forward traffic not only based on hostname but also on a URL path would allow more granular routing.
   Example: domain.com/api/* && 192.168.1.10/app/*
   This would bring advanced flexibility similar to Traefik or Caddy.

Additional security features inspired by NPMplus

More granular access rules

Optional WAF-like filters

Advanced rate-limiting options

Security presets for common use cases
These enhancements would help users better secure their public services without requiring external tools.

The issue names no files, tests, or code entry points; start by mapping the proxy-host routing and security areas affected by each requested enhancement. Done would require separate scope and acceptance criteria for HTTP/3, path-based forwarding, access rules, WAF-like filters, rate limiting, and security presets.
