This provides an option for #223 without fully resolving it. (I think.)
Essentially, it acts very similar to the `gzip_static` and similar options for nginx, where it will check for the existence of pre-compressed files and serve those instead if the client allows it. I couldn't find a pre-existing way to actually parse the Accept-Encoding header properly (admittedly didn't look very hard) and just implemented one on my own that should be fine.
This should hopefully not have the same DOS vulnerabilities as #302, since it relies on the existing caching system. Compressed versions of files will be cached just like any other files, and that includes cache for missing files as well.
The compressed files will also be accessible directly, and this won't automatically decompress them. So, if you have a `tar.gz` file that you access directly, it will still be downloaded as the gzipped version, although you will now gain the option to download the `.tar` directly and decompress it in transit. (Which doesn't affect the server at all, just the client's way of interpreting it.)
----
One key thing this change also adds is a short-circuit when accessing directories: these always return 404 via the API, although they'd try the cache anyway and go through that route, which was kind of slow. Adding in the additional encodings, it's going to try for .gz, .br, and .zst files in the worst case as well, which feels wrong. So, instead, it just always falls back to the index-check behaviour if the path ends in a slash or is empty. (Which is implicitly just a slash.)
----
For testing, I set up this repo: https://codeberg.org/clarfonthey/testrepo
I ended up realising that LFS wasn't supported by default with `just dev`, so, it ended up working until I made sure the files on the repo *didn't* use LFS.
Assuming you've run `just dev`, you can go directly to this page in the browser here: https://clarfonthey.localhost.mock.directory:4430/testrepo/
And also you can try a few cURL commands:
```shell
curl https://clarfonthey.localhost.mock.directory:4430/testrepo/ --verbose --insecure
curl -H 'Accept-Encoding: gz' https://clarfonthey.localhost.mock.directory:4430/testrepo/ --verbose --insecure | gunzip -
curl -H 'Accept-Encoding: br' https://clarfonthey.localhost.mock.directory:4430/testrepo/ --verbose --insecure | brotli --decompress -
curl -H 'Accept-Encoding: zst' https://clarfonthey.localhost.mock.directory:4430/testrepo/ --verbose --insecure | zstd --decompress -
```

This PR add the `$NO_DNS_01` option (disabled by default) that removes the DNS ACME provider, and replaces the wildcard certificate by individual certificates obtained using the TLS ACME provider.
This option allows an instance to work without having to manage access tokens for the DNS provider. On the flip side, this means that a certificate can be requested for each subdomains. To limit the risk of DOS, the existence of the user/org corresponding to a subdomain is checked before requesting a cert, however, this limitation is not enough for an forge with a high number of users/orgs.

Hello 👋
since it affected my deployment of the pages server I started to look into the problem of the blank pages and think I found a solution for it:
1. There is no check if the file response is empty, neither in cache retrieval nor in writing of a cache. Also the provided method for checking for empty responses had a bug.
2. I identified the redirect response to be the issue here. There is a cache write with the full cache key (e. g. rawContent/user/repo|branch|route/index.html) happening in the handling of the redirect response. But the written body here is empty. In the triggered request from the redirect response the server then finds a cache item to the key and serves the empty body. A quick fix is the check for empty file responses mentioned in 1.
3. The decision to redirect the user comes quite far down in the upstream function. Before that happens a lot of stuff that may not be important since after the redirect response comes a new request anyway. Also, I suspect that this causes the caching problem because there is a request to the forge server and its error handling with some recursions happening before. I propose to move two of the redirects before "Preparing"
4. The recursion in the upstream function makes it difficult to understand what is actually happening. I added some more logging to have an easier time with that.
5. I changed the default behaviour to append a trailing slash to the path to true. In my tested scenarios it happened anyway. This way there is no recursion happening before the redirect.
I am not developing in go frequently and rarely contribute to open source -> so feedback of all kind is appreciated
