This PR builds on top of #447 and will be subject to the same discussion. Let's discuss there whether it makes sense to get rid of the `flake-parts` and `git-hooks` flake inputs.

The goal is to contain the “`mkFlake` hack” to a file that we can heavily document but otherwise ignore. This also will allow me to reuse it in the “flake under test” of the deployment tests.

@Niols the sheer amount of hassle and noise indicates that it may be better to first split out a `flake.nix` just for the tests. And all this clutter doesn't even explain yet *why* we thought it needs to be there.
closes#279.

This PR adds a basic deployment test to the repository. This test will, in a NixOS test, run a deployer VM and a target VM, and check that we manage to run `nixops4 apply` on the deployer VM to change things on the target VM. The ideas are all @roberth's and this test has been extremely heavily inspired by https://github.com/nixops4/nixops4-nixos/blob/main/test/default/nixosTest.nix.

adds a deploy button to the panel form - covers the local part of #76.
As a workaround to pass info (from our user form) into nixops4 uses
environment variable `DEPLOYMENT` thru nix's
`--extra-experimental-features configurable-impure-env`.
This setup is greatly inspired by the one used for [0], although with
notable modifications, such as:
- a SASS preprocessor and CSS compressor
- more streamlined NixOS integration tests
- cleaned up service configuration
- a few notes on how to do things better in the future

Apart from cloning the Nix setup, there were additional steps:
- Create an empty `src` directory, since the package requires it
- In the development shell, run `django-admin startproject panel src`
Note that while you can already do
```bash
manage migrate
manage runserver
```
the NixOS integration tests will fail, since `settings.py` needs
careful massaging to expose knobs that can be turned from our systemd
wrapper. The required changes are introduced in the next commit to make
them observable.

Out of date and somewhat simplistic, but serves as a reasonable
example for what can be done
I chose the variant I'm intimately familiar with in order to be able to
pass on knowledge or help with maintenance. But for the future
I strongly recommend picking the good bits from the other
implementations that control complexity in static configuration parts
through Nix expressions.
