The production server is running IPv6-only and has been broken for a
while because by default, Docker refuses to do IPv6 networking. This can
be fixed by adding a custom network to the compose file. Java will still
try to use IPv6, but this can be worked around by setting the
_JAVA_OPTIONS environment variable.

The previous types were lying a bit: by having e.g. KeyStats extend
Record<ColumnId, ...> TypeScript it to have all the properties of
ColumnId, even though it only had some of them. Also, instead of
copy-pasting definitions from the backend types to RenderedData, it is
now built from TS utility types to remove potential for errors.

This enabled removing some copy-pasting in App.tsx where the rendered
data was being created.

It also required some extra casts in Reducer.ts's
compareStocksByAttribute method. Also, instead of filtering the stocks
list to ensure the compared property exists (which now had type errors),
the comparison method handles `undefined` values properly.

Nothing too noteworthy. MariaDB removed mysql compatibility symlinks in
v11 so now Docker compose files need to use mariadbd instead of mysqld
as the entrypoint.

This avoids a bunch of manual one-time set-up for the server, e.g.
installing Docker and creating a systemd service. This also removes a
dependency on some third party GitHub actions.
