feat(inbounds): align tunnel, tun, and hysteria UI with Xray docs

* tunnel: rename settings to Xray's current schema (address →
  rewriteAddress, port → rewritePort, network → allowedNetwork) in
  the model, form modal, info modal, and the bundled API inbound
  template; expose portMap so per-port forwarding can be configured
  from the panel.
* tun: add the full TUN protocol form and read-only info blocks
  (name, mtu, gateway, dns, userLevel, autoSystemRoutingTable,
  autoOutboundsInterface) — previously the protocol was selectable
  but the form rendered blank.
* hysteria: surface the stream-level version, obfs password, and
  udpIdleTimeout fields that the model already supported.
