feat: add smart base image management to pipeline

Pipeline now handles base image automatically:

✅ ensure-base-image:
   • Checks if Dockerfile.base changed
   • Only rebuilds if needed
   • Saves ~10 minutes when unchanged

✅ build-and-push-app:
   • Uses base image
   • Fast build (~3 minutes)

✅ verify-images:
   • Confirms both images exist
   • Shows available tags

Behavior:
─────────
1️⃣  Dockerfile.base changed:
    → Build base (~10 min)
    → Build app (~3 min)
    → Total: ~13 min

2️⃣  Only code changed:
    → Skip base (path filter)
    → Build app (~3 min)
    → Total: ~3 min ✅

This is the smart solution we wanted!
