fix: pin better-auth 1.6.23, drop stale CLI, programmatic migrations, fix CI

- Explicitly track latest core (1.6.23); the @better-auth/cli lags at 1.4.21 and
  pulled a second core copy — replaced with a getMigrations() script on the same
  version (src/migrate.ts).
- CI build job matches the proven pattern (no setup-buildx; plain build/push).
