fix(iace): stronger relevance filter + matcher wrong-machine penalty

Relevance filter: now checks PatternName in addition to ZoneDE+ScenarioDE,
catches "Spielplatz", "Umreifungsband", "Fahrtreppe" etc. in pattern names.
Added more generic safety terms to whitelist (welle, getriebe, kette, etc.)

Matcher: rebalanced weights (category 0.3, keywords 0.3, zone 0.4) to
prioritize zone/component specificity. Added wrong-machine penalty (0.3x)
when engine hazard mentions machine-specific terms absent from GT context
(e.g. "Kollision zweier Roboter" for a single-robot GT entry).

Fixes 18 problematic matches: 8 wrong-machine, 9 zone-mismatch, 1 category.
