feat(iace): FMEA source-document register + Anthropic extraction (Haiku)

Quote-verifiable failure extraction via Claude (Haiku 4.5): PDF sent
directly, tool-schema forces verbatim source quotes + applicable flag +
confidence — replaces the unreliable local llama run. Only applicable=true
tuples ingest into bp_iace_failure_kb; every processed doc lands in the
source manifest.

Frontend: FMEA tab now shows a "Quelldokumente" register (every document we
use, with source + licence + link + what was extracted) served from the
embedded manifest via GET /iace/failure-knowledge/sources. Manifest is
placeholder until the 100-doc Haiku run is folded in.
