many issues occur with setup, all this does is tell the user something
bad happened and to check the logs. Might help with solving issues.
Also fixed some now invalid typescript.
New "Access jfa-go" column allows you to select users for jfa-go access.
New "Allow All" setting allows all Jellyfin users access, as disabling
"Admin Only" no longer does this.
Also changed some section names to use "messages" instead of "emails".
Since I haven't added Discord/Telegram/Matrix bot setup, I mentioned you
can do these later and linked to the setup guides. Sections related to
email mostly now depend on [messages]/enabled now too. Set password via
link has been added to password resets.
Also make store each setting as classes in a settings object, to make it
easier to serialize on submitting. Also, added
"substitute_jellyfin_strings", "no_username" and welcome_email.
