Better Auth rate_limit table migration exists on branch but hasn't
been deployed to UAT. Switching to memory storage bypasses the
missing table entirely, restoring auth functionality immediately.
Memory storage is per-instance (not shared) — rate limiting still
functions but won't be distributed across pods. This is acceptable
for UAT while the migration is being promoted through the pipeline.
