fix(ai): language-aware prompt, better insights, larger spinner

- Prompt respects user locale (de/en/fr/es/it/pt) — responds in user's language
- Rewrite prompt: domain pattern analysis, low-click diagnosis, no generic advice
- Include total clicks + link count for context
- max_tokens 512 → 800 for richer output
- Button spinner: h-5 w-5 (was h-4 w-4), bg-inherit to cover label text cleanly
