fix: Struktureller Fix — Maschinentyp-Filter fuer Keywords + Patterns

PROBLEM: Cobot-Projekt hatte 52 Pressen-Hazards weil Keywords wie
"stempel" und "stoessel" ohne Maschinentyp-Kontext matchten.

FIX an 3 Stellen:
1. KeywordEntry.MachineTypes — Pressen-Keywords nur fuer press/*_press
2. ParseNarrative(text, machineType) — Parser laedt Maschinentyp aus Projekt
3. HazardPattern.MachineTypes — Pressen-Patterns (HP045-HP058) nur fuer Pressen

Verhindert zukuenftig falsche Zuordnungen bei neuen Kundenprojekten.
