[Feature Request] HTTPS support

[AriaMoradi]

What feature should be added to Tachidesk?

Run the server in HTTPS mode.

Why/Project's Benefit/Existing Problem

Combined with basic auth, allows a more secure experience.

Additional notes

• Implementation is probably relatively easy, both javalin and jetty provide examples.
• The current recommended way to get HTTPS with Tachidesk is running with a reverse proxy server.
• Input by @ntbm "I really prefer configuring my reverse proxy and managing the certificates outside of an application. So usecase are people who want to host it on a server, but are not really familiar with hosting?"
• Input by @Derevar on discord: "My prefered way is app in a docker and that behind my nginx reverse proxy." They also agree with @ntbm.
• My current conclusion: Our users don't seem to need this feature really, also managing certificates with an app outside Tachidesk is indeed better.
