Extracted the other logic to its current singular callsite for now.
The load_or_create function finally does nothing other than load or
create the database (and do some related checks, which is fine). This
paves the way for more/better database surgery tooling.
* Database load function is the wrong place for this
* There's no good lower bound to check for this
* Surely people setting this to a small value would realize what they're
in for
This method did _a lot_ of things at the same time. In order to use
`KeyValueDatabase` for the migrate-db command, we need to be able to
open a db without attempting to apply all the migrations and without
spawning a bunch of unrelated background tasks.
The state after this refactor is still not great, but it's enough to do
a migration tool.

tokio::spawn is a span boundary, the spawned future has no parent span.
For short futures, we simply inherit the current span with
`.in_current_span()`.
For long running futures containing a sleeping infinite loop, we don't
actually want a span on the entire task or even the entire loop body,
both would result in very long spans. Instead, we put the outermost span
(created using #[tracing::instrument] or .instrument()) around the
actual work happening after the sleep, which results in a new root span
being created after every sleep.
This change is fully automated, except the `rustfmt.toml` changes and
a few clippy directives to allow specific functions with too many lines
because they are longer now.
This makes it possible to deploy Grapevine while using a database
originally created by Conduit, including leaving the admin bot user's
localpart the same as before.
