Spells, agents, etc should be isolated to per-account

[lalalune]

Right now with the current Thoth server we are not giving per-user access to spells, personalities, agents, knowledge bases, etc.

When running in our default, non-Latitude mode, user accounts are kind of a headache, so we probably want to just default to a default user. If someone wants to add a non-Latitude login system in the future for multi-tentant Thoth instances, they certainly can.

Yeah. I think if we get it all sorted so it "just works" with a latitude SSO, that is fine. And if anyone has. strong use case for not storing the data against a latitude user ID in the DB, then we can always be open to PR's or do it ourselves if there is a strong cause to do so.
