Malin 8d4eaa1489 feat: add full Zonemaster stack with Docker and Spanish UI
- Clone all 5 Zonemaster component repos (LDNS, Engine, CLI, Backend, GUI)
- Dockerfile.backend: 8-stage multi-stage build LDNS→Engine→CLI→Backend
- Dockerfile.gui: Astro static build served via nginx
- docker-compose.yml: backend (internal) + frontend (port 5353)
- nginx.conf: root redirects to /es/, /api/ proxied to backend
- zonemaster-gui/config.ts: defaultLanguage set to 'es' (Spanish)

# Installation: Zonemaster-LDNS
## Recommended installation
The recommended way to install Zonemaster::LDNS is to follow the
[installation instructions for Zonemaster::Engine] where you will find all
prerequisites and dependencies for Zonemaster::LDNS before installing it.
## Installation from source
Override the default set of features by appending `--FEATURE` and/or
`--no-FEATURE` options to the `perl Makefile.PL` command.
```sh
git clone https://github.com/zonemaster/zonemaster-ldns
cd zonemaster-ldns
perl Makefile.PL
make
make test
make install
```
> **Note:** The source ZIP files downloaded from GitHub are broken with
> respect to this instruction.
### Optional features
When installing from source, you can choose to enable or disable a number
of optional features using command line options to the `perl Makefile.PL`
commands.
#### Ed25519
Enabled by default.
Disabled with `--no-ed25519`
Requires support for algorithms Ed25519 and Ed448 in both openssl and ldns.
>
> *Note:* Zonemaster Engine relies on this feature for its analysis when Ed25519
> (DNSKEY algorithm 15) or Ed448 (DNSKEY algorithm 16) is being used in DNSSEC
> signatures.
>
#### IDN
Enabled by default.
Disable with `--no-idn`.
If the IDN feature is enabled, the GNU `libidn2` library will be used to
add a simple function that converts strings from Perl's internal encoding
to IDNA domain name format.
In order to convert strings from whatever encoding you have to Perl's
internal format, use L<Encode>.
If you need any kind of control or options, use [Net::LibIDN].
The included function here is only meant to assist in the most basic case,
although that should cover a lot of real-world use cases.
> **Note:** The Zonemaster Engine test suite assumes this feature
> is enabled.
#### Internal ldns
Enabled by default.
Disable with `--no-internal-ldns`.
When enabled, an included version of ldns is statically linked into
Zonemaster::LDNS.
When disabled, libldns is dynamically linked just like other dependencies.
#### Custom OpenSSL
Disabled by default.
Enabled with `--prefix-openssl=/path/to/openssl` or
`--openssl-inc=/path/to/openssl_inc` or `--openssl-lib=/path/to/openssl_lib`.
Enabling this makes the build tools look for OpenSSL in a non-standard place.
Technically this does two things:
* Libcrypto is sought in the `lib` directory under the given directory.
* The `include` directory under the given directory is added to the include
path.
> **Note:** The `lib` directory under the given path must be known to the
> dynamic linker or feature checks will fail.
If both headers and libraries directories (`include` and `lib`) are not in the
same parent directory, use `--openssl-inc` and `--openssl-lib` options to
specify both paths.
#### Custom LDNS
Disabled by default.
Enabled with `--ldns-inc=/path/to/ldns_inc` or `--ldns-lib=/path/to/ldns_lib`.
Enabling this makes the build tools look for LDNS in a non-standard place.
> Requires [Internal LDNS] to be disabled.
#### Custom Libidn
Disabled by default.
Enabled with `--libidn-inc=/path/to/libidn_inc` or
`--libidn-lib=/path/to/ldns_lib`.
Enabling this makes the build tools look for Libidn in a non-standard place.
> Requires [IDN] to be enabled.
#### Debug
Disabled by default.
Enabled with `--debug`.
Gives a more verbose output.
## Post-installation sanity check
```sh
perl -MZonemaster::LDNS -E 'say Zonemaster::LDNS->new("8.8.8.8")->query("zonemaster.net")->string'
```
The above command should print some `dig`-like output.
### Testing
Some of the unit tests depend on data on the Internet, which may change. To avoid
false fails, those unit tests are only run if the environment variable
`TEST_WITH_NETWORK` is `true`. By default that variable is unset (those tests are
not run). To run all tests, execute
```sh
TEST_WITH_NETWORK=1 make test
