Starts pgvector (8000), Oracle 26ai (8001), and Oracle in-DB (8002)
backends concurrently and stops all on Ctrl+C.

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/.

Each backend now mounts its frontend directory at /ui/ so the UIs are
accessible via http://localhost:800x/ui/ instead of file:// URLs.

Three FastAPI backends comparing PostgreSQL/pgvector and Oracle 26ai for

databases, plus Oracle in-database embedding via VECTOR_EMBEDDING(CLIP_TXT).
