feat(hysteria2): emit UDP port hopping in subscriptions and share links

Browse Source 
UDP Hop (finalmask.quicParams.udpHop.ports) was configurable but never surfaced in generated configs, so clients kept using the single listening port (#4789).

Share links (frontend genHysteriaLink + sub genHysteriaLink) now keep a numeric port in the authority and carry the hop range as the v2rayN-compatible mport query param, so v2rayN and other System.Uri-based importers can parse the link. Clash output sets mihomos native ports field.

Closes #4789
