Description

If this is a code change, please include a summary of what you've coded, and link to the issue(s) it closes/implements.

If this is a documentation change, please briefly describe what you've changed and why.

This pull request adds db functions, API endpoints, and settings panel stuff for viewing token info, and invalidating tokens.

Closes #1573

Builds on #3849 so I'll rebase this after that one gets squerged.

Still a draft while I write tests + docs.
