Due to failing docker builds it was brought to our attention,
that the backend relied on the uuid package without declaring
it as dependency. This worked in all development and build
scenarios as the frontend declares uuid as dependency already
and top-level `yarn install` installs all dependencies from all
workspaces. However as the docker build only runs for either
the backend or the frontend, this failed.
This commit adds the dependency to the backend as well.

The API documentation belongs strictly to the API itself.
Due to the usage of version-prefixed API endpoints, there is no conflict
with existing or future endpoints.
The reason behind this is that we already have enough exceptions in the
routing (default everything to react-frontend, exceptions for backend)
and it is hard to keep it synchronized throughout all relevant places.
This came to attention as the dev setup didn't proxy the API docs to the
backend.

Thanks to all HedgeDoc team members for the time discussing,
helping with weird Nest issues, providing feedback
and suggestions!

OWASP [1] recommends for password hashing the following algorithms in
descending order: argon2id, scrypt, bcrypt. They state that bcrypt may
be used in legacy systems or when required due to legal regulations.
We're however not building any legacy application. Even HedgeDoc 1.x
utilizes a more modern algorithm by using scrypt.
While bcrypt is not insecure per se, our implementation had a major
security flaw, leading to invalid passwords being accepted in certain
cases. The bcrypt nodejs package - and the OWASP cheatsheet as well -
point out, that the maximum input length of passwords is limited to 72
bytes with bcrypt. When some user has a password longer than 72 bytes in
use, only the first 72 bytes are required to log in successfully.
Depending on the encoding (which could be UTF-8 or UTF-16 depending on
different circumstances) this could in worst-case be at 36 characters,
which is not very unusual for a password. See also [2].
This commit changes the used algorithm to argon2id. Argon2id has been in
use for several years now and seems to be a well-designed password
hashing function that even won the 2015 Password Hashing Competition.
Argon2 does not have any real-world max input length for passwords (it
is at 4 GiB).
The node-rs/argon2 implementation seems to be well maintained, widely
used (more than 150k downloads per week) and is published with
provenance, proving that the npm package was built on GitHub actions
using the source code in the repository. The implementation is written
in Rust, so it should be safe against memory leakages etc.

When the frontend is notified about metadata updates, it refreshes the
data and therefore refreshes information like the timestamp of the last
revision save in the sidebar.
This commit adds such a notification from the backend to all clients on
each revision save, so that the "last saved at" value in the frontend is
correct.

When creating a new note or adding a new alias to one,
it is checked that the new name
is neither forbidden nor already in use.

Previous versions of HedgeDoc suffered from the problem
that changing the media backend required manipulation of
the media links in all created notes. We discussed in
#3704 that it's favourable to have an endpoint that
redirects to the image's original URL. When changing the
media backend, the link stays the same but just the
redirect changes.
