v1.2.0 — Card Match persona + intent ranking

What's new

• Card Match finder — select a persona, then filter by specific intents (e.g. Shopee, siêu thị) nested as sub-chips
• Scope-aware cashback labels — catchall rules now show the correct scope: Online, Offline, quốc tế, nội địa instead of generic "Tất cả chi tiêu"
• Rate on intent chips — each intent badge shows its cashback rate (e.g. 🛍️ Shopee 5%)
• Ranking POST includes selected intents; falls back to persona default when none selected

Fixes

• getIntents() path corrected to /api/v1/meta/intents
• CashbackRule type extended with scope field (channel + geography)

• LLM-as-judge evaluator — auto-scores live chat traces for hallucination detection via Langfuse Evaluators
