Since this is reported as a generic 'something-is-wrong' error message, I suspect it may be related to the errors that I see in the catalina.out:

Welcome to the Atlassian Community!
That looks like your database is misconfigured. The user access error is only the first problem that your system is likely to encounter when your database isn't working.
You're going to need to get your database set up correctly first, and probably then restore from a backup, as the data may have been damaged while Jira is trying to use it in a broken state.
It's not the server that is creating the database - you have to do the basics, getting to an empty database that the server can then add things into.

Is there are separately runnable script that _only_ runs the sql commands to write the initial data into the database? That would be amazingly useful.

Um, run the installer?
Your problem is not with the content of the database, it is mis-configured, so Jira can't use it.
