dierk 31ea0143d0 Fix in-DB frontend serving its own index.html instead of the Oracle 26ai one 
Moved index_indb.html into a dedicated frontend/indb/ subdirectory so the
in-DB backend (port 8002) serves the correct purple Oracle In-DB UI at /ui/.

dierk 4e68b2f226 Serve frontends via FastAPI static files to fix Brave browser file access block 
Each backend now mounts its frontend directory at /ui/ so the UIs are
accessible via http://localhost:800x/ui/ instead of file:// URLs.

semantic image search using CLIP embeddings: Python-side embedding for both
databases, plus Oracle in-database embedding via VECTOR_EMBEDDING(CLIP_TXT).
