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. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

"""Quote-verifiable FailureKnowledge extraction via the Anthropic API.
|
||||
|
||||
Sends each NASA NTRS PDF DIRECTLY to Claude (native PDF + vision, incl. scanned)
|
||||
and forces a structured tool call whose schema REQUIRES a verbatim source quote
|
||||
for the key fields — every value is auditable against the document. Only
|
||||
public-reuse-licensed NTRS docs are processed. applicable=true tuples are
|
||||
ingested into bp_iace_failure_kb; EVERY processed doc is recorded in the source

manifest (used vs checked-not-used) for the FMEA frontend register.
