RetrieX answer grounding strictness fix

Patch scope:

• Strengthens prompt/grounding rules for technical product-selection answers.
• Keeps Retrieval, Shop Search, AgentRunner, SSE, and scoring untouched.
• Prevents confident suitability claims from weak shop hits or query wording.
• Explicitly prevents treating p-Wert/m-Wert/minus m-Wert as pH/pH-Wert unless the same source says pH or pH-Wert.
• Forces short, source-close answers when evidence is uncertain.

Expected effect for cases like: "suche einen testomat der ph messen kann"

RetrieX should not confidently turn p-Wert into pH-Wert, should not invent measurement principles/benefits/alternatives, and should say when technical suitability is not securely proven by the provided RAG/shop records.
