* core: Apply SO_REUSEPORT to UDP sockets
For some reason, 10 months ago when I implemented SO_REUSEPORT
for TCP, I didn't realize, or forgot, that it can be used for UDP too. It is a
much better solution than using deadline hacks to reuse a socket, at
least for TCP.
Then https://github.com/mholt/caddy-l4/issues/132 was posted,
in which we see that UDP servers never actually stopped when the
L4 app was stopped. I verified this using this command:
$ nc -u 127.0.0.1 55353
combined with POSTing configs to the /load admin endpoint (which
alternated between an echo server and a proxy server so I could tell
which config was being used).
I refactored the code to use SO_REUSEPORT for UDP, but of course
we still need graceful reloads on all platforms, not just Unix, so I
also implemented a deadline hack similar to what we used for
TCP before. That implementation for TCP was not perfect, possibly
having a logical (not data) race condition; but for UDP so far it
seems to be working. Verified the same way I verified that SO_REUSEPORT
works.
I think this code is slightly cleaner and I'm fairly confident this code
is effective.

* Browse.html: Add canonical URL and home-link
When contents are equal, but maybe just a sort order is different, it is good to add `<link rel="canonical" href="base-path/" />`. This helps search engines propeely index the page.
I also added a link to the home page with the name of `{{.Host}}` just above the bread crumbs to make the page clearer.

* Update browse.html
* reverseproxy: Add more debug logs
This makes debug logging very noisy when reverse proxying, but I guess
that's the point.
This has shown to be useful in troubleshooting infrastructure issues.

* Enhancement: Allow X-Forwarded-For Header in httpInclude Virtual Requests
The goal of this enhancement is to modify the funcHTTPInclude function in the Caddy codebase to include the X-Forwarded-For header in the virtual request. This change will enable reverse proxies to set the X-Forwarded-For header, ensuring that the client's IP address is correctly provided to the target endpoint. This modification is essential for applications that depend on the X-Forwarded-For header for various functionalities, such as authentication, logging, or content customization.
* Updated tplcontext.go - set `virtReq.RemoteAddr = "127.0.0.1"`
i have made the suggested changes
* Apply suggestions from code review
