fix(api): use notInArray + inArray in unread-count subqueries

the sql.join() form of NOT IN crashed the route handler before
it could respond — vercel surfaced the crash as a plaintext 404
instead of going through hono's exception handler. switching to
drizzle's notInArray() / inArray() emits stable parameter
bindings and resolves both /v1/me/topics (fresh endpoint) and
/v1/topics (older endpoint with the same ANY() pattern bug).

also cleans up debug instrumentation that was added while
chasing the 404.
