refactor(fase1c): routing S3 fixes + auth/swagger/index/env

- routes: GET / teruskan headers ke shouldHandleS3; OPTIONS jawab
  204 CORS generik bila bukan S3, handleS3Direct bila S3; komentar
  bypass rate-limit S3 dipertahankan (registry abort pada 429)
- auth-controller: readLoginBody via LoginBodySchema; handleMe sederhanakan
  (getAuthSession sudah cek bearer); import AuthSession dari dto
- swagger: pindah src/routes -> src/interfaces/http/swagger; tambah path
  auth, /api/v1, /{bucket}, /{bucket}/{key}; version dari config.appVersion
- index: unref ketiga setInterval agar tak menahan process
- env: PORT fail-fast via PositiveIntSchema (default 4000 bila tak diset);
  log config turun ke debug
- metrics: dokumentasikan uploadThroughput/queueSize/botUtilization
- test baru test/s3-routing.test.ts (GET / S3 vs home, OPTIONS 204 CORS)
