Remove unnecessary await/async from sync bun:sqlite db calls

drizzle-orm/bun-sqlite is fully synchronous — all queries return values
directly, not promises. Remove await from all db calls, drop async from
functions that no longer need it, simplify Promise.all patterns that
wrapped sync operations, and fix setSetting() which was missing .run()
(previously masked by await triggering execution via thenable).
